5. Click OK in the next dialog boxes.
You cannot install Internet Explorer 5.5 Service Pack 2 and Internet
Tools to or run it from a network drive. However, you can download
itto a network drive. To do this, you must map the network drive
to a drive letter on your computer; you cannot download
Internet Explorer 5.5to a UNC path.
Running Internet Explorer 5.5 Service Pack 2 on Microsoft
Windows NT 4.0
---------------------------------------------------------
Note:
You must have administrative privileges to install
and uninstall this program on Windows NT. This includes
having administrative privileges the first time you
start your computer after installing or uninstalling.
You must restart your computer after installing Internet Explorer
5.5 and Internet Tools. This is also true for some add-on
components.
For corporate deployment on computers running Windows NT 4.0,
make sure you have the following free registry space:
- If you are upgrading from Internet Explorer 2.0 or
Internet Explorer 3.x: at least 4 MB
- If you are upgrading from Internet Explorer 4.x:
at least 2.5 MB
If you're running Internet Explorer 5.5 Service Pack 2 on
Windows NT 4.0, you must set user permissions to Full Control for
the Temporary Internet Files folder (cache). The user must have write
permission so that files can be stored in the Temporary Internet
Files folder.
If you must reinstall Windows NT 4.0 Service Pack 3 (SP3) after you
install Internet Explorer 5.5 Service Pack 2 and Internet Tools, you
must specify when prompted that you do not want it to overwrite any
files that are newer. After SP3 is reinstalled, carry out the
following steps to update the registry:
1. Click the Start button, and then click Run.
2. Type the following: regsvr32 rsabase.dll
Installing Windows NT 4.0 Service Packs over Internet Explorer 5.5
------------------------------------------------------------------
If you reinstall a Windows NT 4.0 Service Pack after Internet
Explorer 5.5 Service Pack 2 and Internet Tools is installed on your
computer, some components will need to be re-registered. To do this,
carry out the following steps:
1. In Control Panel, double-click Add/Remove Programs.
2. On the Install/Uninstall tab, click Microsoft Internet Explorer
5.5 Service Pack 2 and Internet Tools.
3. Click Add/Remove.
4. Click Repair Internet Explorer, and then click OK.
5. After the repair operation is complete, restart your computer.
Installing over Windows 2000 Releases
-------------------------------------
Typical and Full installations are not currently available for
Windows 2000. Internet Explorer 5.5 Service Pack 2 will install
a default set of files into your computer; this includes the
Internet Explorer 5.5 Service Pack 2 Web browser, Outlook Express
and scripting support.
Uninstall Internet Explorer 5.5 Service Pack 2 Before Upgrading to
Windows 2000
-------------------------------------------------------------------
Windows 2000 contains an earlier version of Internet Explorer
components. When upgrading from Windows 95, Windows 98, or
Windows NT to Windows 2000, we recommend that you uninstall
Internet Explorer 5.5 Service Pack 2 before the upgrade.
Uninstall Internet Explorer 5.5 Service Pack 2 Before Installing
Windows 2000 Service Pack(s).
-------------------------------------------------------------------
Windows 2000 Service Pack(s) contain an earlier version of
Internet Explorercomponents. Before installing a Windows 2000
Service Pack, we recommend that you uninstall Internet Explorer 5.5
Service Pack 2 before the upgrade. You may then reinstall
Internet Explorer 5.5 Service Pack 2.
Downloading Internet Explorer by Using Third-Party Download Manager
-------------------------------------------------------------------
During the Internet Explorer 5.5 Service Pack 2 and Internet Tools
installation, Setup must download components from the Internet. If
you are using third-party download managers (for example, Netzip or
GetRight) they will intercept the download request. This will cause
Setup to stop. To prevent this from occurring, first disable
third-party download managers, and then run Setup.
High Encryption Support For Internet Explorer 5.5 Service Pack 2
----------------------------------------------------------------
High Encryption components are available on Windows 95, Windows 98,
Windows 98 Second Edition, Windows Me, and Windows NT 4.0. To obtain
high-encryption support for Windows 2000, please visit Windows Update
or http://www.microsoft.com/windows2000/downloads/recommended/
encryption/default.asp
Enhanced Encryption Strength
----------------------------
Internet Explorer 5.5 now ships with a standard encryption strength
of 128 bits and supports the U.S. government standard for data
encryption (DES). 128-bit Internet Explorer 5.5 is eligible for
distribution to all users worldwide except in U.S.-embargoed
destinations. For more information, visit the following Web site: http://www.microsoft.com/exporting/
Running Internet Explorer 5.5 Service Pack 2 on a Dual-Boot
Operating System
-----------------------------------------------------------
If you are running Internet Explorer 5.5 Service Pack 2 on a computer
that is set up to dual boot between two operating systems on the same
partition (for example, Windows 95 and Windows NT 4.0), and you have
configured the computer to share a single Program Files folder, you
might have problems with add-on components.
Also, when you uninstall an add-on component from either copy of
Internet Explorer 5.5, it will be removed from both of them without
updating the other operating system's installed components information.
These problems occur because the add-on files are all stored in the
shared Program Files folder, but information about installed add-on
components is stored elsewhere.
Installing or Upgrading the Windows Desktop Update (NT4 only)
--------------------------------------------------------------
To install or upgrade the Windows Desktop Update, you must install
Internet Explorer 4.01 SP2 before you install Internet Explorer 5.5
and Internet Tools.
If you have already installed Internet Explorer 5.5 and would like to
install the Windows Desktop Update, carry out the following steps:
1. Uninstall Internet Explorer 5.5 Service Pack 2 by using the
procedure listed later in this document.
2. If Internet Explorer 4.01 SP2 is not already installed on your
computer, install it.
3. Install the Windows Desktop Update by using Add/Remove Programs
in Control Panel.
4. Reinstall Internet Explorer 5.5 Service Pack 2 and Internet Tools.
Installing over Localized Windows 98 Arabic and Hebrew Releases
---------------------------------------------------------------
Windows 98 Arabic and Hebrew versions require the corresponding
localized version of Internet Explorer 5.5. It is not possible to
install the English version of Internet Explorer over the localized
version of Windows 98.
This restriction does not apply to localized versions of Windows 95
or Windows NT 4.0. However, you cannot install localized Arabic or
Hebrew Internet Explorer 5.5 Service Pack 2 over localized Windows 95
(only English is supported).
Installing Outlook Express 5.x on Windows Terminal Server
---------------------------------------------------------
Before installing Outlook Express 5.x on Windows Terminal Server,
the administrator needs to set a compatibility flag in the registry
in order for the Outlook Express 5.x Setup program to work correctly.
To do this, carry out the following steps:
1. Create this registry key:
HKEY_LOCAL_MACHINE\Microsoft\Windows NT\CurrentVersion\
Terminal Server\Compatibility\Applications\setup50
2. Set the following value under the new setup50 key (this value
should be of type REG_DWORD):
Flags = 0x108
Installing on Windows 98 with Novell IPX/IP Client
--------------------------------------------------
If you are using Novell IPX/IP client with Windows 98, you might
experience problems if you install Internet Explorer 5.5 and Internet
Tools from the Internet. If Setup appears to become unresponsive,
restart your computer. Setup will continue and finish normally. To
work around this problem, try one of the following options:
- In Setup, select the Download Only option, and then run and install
Internet Explorer 5.5 Service Pack 2 normally.
- Install Internet Explorer 5.5 Service Pack 2 from a CD-ROM.
Uninstalling Internet Explorer 5.5 Service Pack 2 and Internet Tools
--------------------------------------------------------------------
You can uninstall Internet Explorer 5.5 Service Pack 2 and Internet
Tools by carrying out the following steps:
1. In Control Panel, double-click Add/Remove Programs.
2. Click Microsoft Internet Explorer 5.5 Service Pack 2 and Internet
Tools, and then click Add/Remove.
3. Click Restore the Previous Windows Configuration, and then click
OK.
4. Follow the instructions on the screen.
Uninstall for Previous Versions of Internet Explorer Unavailable
----------------------------------------------------------------
If you uninstall Internet Explorer 5.5 Service Pack 2, you will
not be able to remove the browser that was installed prior to
Internet Explorer 5.5.
Uninstalling Internet Explorer 5.5 Service Pack 2 Returns You to
an Earlier Version
----------------------------------------------------------------
When you install Internet Explorer 5.5 Service Pack 2, Setup examines
your system for the presence of uninstall data that had been created
by a previous installation. If Setup cannot find this data, it creates
new uninstall data for later use.
If you previously upgraded from Internet Explorer 4.x to 5.0 or
5.01, you will have uninstall data that allows you to roll back to
Internet Explorer 4.x. Unless you explicitly removed the uninstall
data using Add/Remove Programs in Control Panel before upgrading to
Internet Explorer 5.5 Service Pack 2, this data will be preserved.
When you uninstall Internet Explorer 5.5 Service Pack 2, it will use
the existing uninstall data and roll back to Internet Explorer 4.x.
The following chart lists the various upgrade scenarios and the
Internet Explorer 5.5 uninstallation behavior that can occur in each
case.
+-------------------------------------------------------------------+
| Previous Version | Uninstall Data | Uninstall Results |
+-------------------------------------------------------------------+
| Internet Explorer 3.x | n/a | Internet Explorer 3.x |
+-------------------------------------------------------------------+
| Internet Explorer 4.x | n/a | Internet Explorer 4.x |
+-------------------------------------------------------------------+
| Internet Explorer 5 | Exists | Pre-Internet Explorer 5 |
| | | version |
+-------------------------------------------------------------------+
| Internet Explorer 5 | Doesn't exist | Internet Explorer 5 |
+-------------------------------------------------------------------+
| Windows 98 | | Windows 98 |
| (Internet Explorer 4) | n/a | (Internet Explorer 4) |
+-------------------------------------------------------------------+
| Windows 98 SE | | Windows 98 SE |
| (Internet Explorer 5) | n/a | (Internet Explorer 5) |
+-------------------------------------------------------------------+
Using Download only
-------------------
In Internet Explorer 5.5, if you select the Download Only option you
will not be able to choose which components are downloaded and which
are not. All the cabinet (.cab) files for a full installation for the
operating system you choose are downloaded. There is no user interface
in Windows 2000 to select Download Only.
To perform a Download Only on Windows 2000, see the following
article in the Microsoft Knowledge Base:
http://support.microsoft.com/support/kb/articles/q257/2/49.asp
Windows 2000 Upgrade Exception Pack
-----------------------------------
Internet Explorer 5.5 Service Pack 2 includes a component called
the Windows 2000 Upgrade Exception Pack. This purpose of the
Exception Pack is to downgrade Internet Explorer 5.5 Service Pack 2
in preparation for upgrade to Windows 2000. Until the computer is
upgraded to Windows 2000, the Exception Pack is not invoked. During
the installation of Windows 2000, the Exception Pack removes
Internet Explorer 5.5 Service Pack 2 registry keys that are no longer
needed or contrary to entries created by Windows 2000; this ensures a
problem-free upgrade.
Outlook Express Removed After Uninstalling Internet Explorer
------------------------------------------------------------
After you uninstall Internet Explorer and Outlook Express 5.01 or
Outlook Express 5.5 from a computer running Windows 98 Second Edition,
the previous version of Outlook Express is not restored. For more
information about this issue, please see the following article in
the Microsoft Knowledge Base:
http://support.microsoft.com/support/kb/articles/q245/3/16.asp
MUI Settings when Upgrading to Internet Explorer 5.5 Service Pack 2
-------------------------------------------------------------------
After upgrading to Internet Explorer 5.5 Service Pack 2 MUI Menu items
may display in English. The language in question may not properly
appear. This can fixed by reinstalling applicable MUI files.
=================
ADDITIONAL ISSUES
=================
FTP User Interface and Functionality
------------------------------------
If you discover an issue in the FTP user interface that blocks FTP
functionality, you can turn off this feature on the Advanced tab in
the Internet Options dialog box.
The following functionality is not supported:
- Internet connection via CERN or Web proxy servers.
- Connecting to VAX or VMS FTP servers.
- Using the browser from within a separate application or service.
- Copying from server to server.
- Drag-and-drop or copy-and-paste functionality from an FTP
server is supported only on Windows 2000, Windows Me, and later.
Font Display Issues
-------------------
If you run a non-Asian language version of Windows NT 4.0 and
you have installed many large fonts, the system's ability to use
those fonts may be exceeded. If Asian language Web pages are not
displayed correctly, install Windows NT 4.0 Service Pack 5.
Non-English Characters in URLs and Queries
------------------------------------------
Internet Explorer 5.5 uses a new standard to transmit non-English
addresses (URLs) to the server. URLs are now encoded in a
character-encoding standard named UTF-8. If the server is running
Windows 2000, the URLs will work as expected. Many servers cannot
process URLs encoded in UTF-8. To use non-English characters in
URLs with these servers, carry out the following steps:
1. On the Tools menu in the browser, click Internet Options.
2. Click the Advanced tab.
3. Under Browsing, clear the Always Send URLs As UTF-8 check box.
The query part of URLs is transmitted in a form fully compatible
with Internet Explorer 4 and above.
Internet Explorer 4.x Compatibility Mode
----------------------------------------
The Internet Explorer 4.x compatibility option is useful to Web
developers who want to view and test their Web sites on different
versions of Internet Explorer, using the same computer. You might
not be able to change all settings for the browser while in this
mode. When using the compatibility option, you should change
Internet options via Control Panel, not through the Internet
Options command on the browser's Tools menu.
Uninstalling Outlook Express 5.x
--------------------------------
If you uninstall Outlook Express 5.x and you were previously running
Microsoft Internet Mail and News, you will be able to see only
the messages you received using Internet Mail and News. To view
Outlook Express 5.x messages, you must reinstall Outlook Express 5.x.
If you uninstall Outlook Express 5.x and you were previously
running Outlook Express 4.x, you can view your Outlook Express 5.x
messages in version 4.x by carrying out the following steps:
1. On the File menu in Outlook Express, click Import, and then
click Messages.
2. In the list of programs, click Microsoft Outlook Express 5.
3. Follow the instructions on your screen.
Radio Toolbar
-------------
Internet Explorer 5.5 Service Pack 2 includes a Radio toolbar that
allows streaming radio playback over the Internet. By default, the
toolbar is not displayed when the browser is started. To display
the toolbar whenever the browser is started, carry out the following
steps:
1. On the Tools menu in the browser, click Internet Options.
2. Click the Advanced tab.
3. Under Multimedia, select the check box labeled Always Show
Internet Explorer (5.0 or Later) Radio Bar.
Changing the Language of Menus and Dialog Boxes
-----------------------------------------------
Changing the language used in menus and dialog boxes might not work
with all display adapters. If you see blank menus or dialog boxes
after changing the language, try either of the following options:
- Change the resolution of your display adapter.
- Upgrade the driver for your display adapter to a newer
version. For information about updated drivers, contact
the manufacturer of your display adapter.
AutoComplete Options
--------------------
If you do not want AutoComplete to suggest matches for certain
sensitive items you have previously entered, you have several
options:
- To delete a specific AutoComplete entry, highlight it in the
AutoComplete drop-down list, and then press DELETE.
- To delete a user name/password combination on a login page,
delete the user name; the password will be deleted with it.
- To clear all form or password information, do the following:
1. On the Tools menu in the browser, click Internet Options.
2. Click the Content tab.
3. Click AutoComplete, and then click Clear Forms or Clear
Passwords.
Operating System Limitations for Character Rotation in Vertical Text
--------------------------------------------------------------------
When working with vertical text layout, full-width (East Asian
language) characters will be displayed with upright orientation
only on East Asian versions of Windows 95, Windows 98, Windows Me,
and Windows NT 4.0 Operating Systems. All language versions of
Windows 2000 provide this support.
Security Settings
-----------------
The settings for the security levels of the Web content zones
have changed for Internet Explorer 5.5 and might no longer be
consistent with those in previous versions of Internet Explorer.
If you upgrade from a previous version of Internet Explorer,
Setup will save your previous security settings and transfer
them to Internet Explorer 5.5 as a Custom Security Level.
Contacts Missing in Address Book After Uninstalling Windows Me
--------------------------------------------------------------
When uninstalling Windows Millennium Edition (Me), contacts that
you added while using Windows Me might be missing from the Windows
Address Book. When you upgrade to Windows Me, the Windows Address
Book data file is backed up. During the uninstallation process,
the backup copy of the data file is restored, overwriting any data
that had been added in Windows Me. To preserve any contacts made
in Windows Me, back up the .wab file(s) before uninstalling.
After Windows Me has been removed, the .wab file(s) can be
recopied back into place and used if Internet Explorer 5.01
or greater is installed.
Outlook Express Title Screen Does Not Match Version
---------------------------------------------------
When you start Outlook Express, the title screen indicates that
the product is "Microsoft Outlook Express 5" even though you
installed a later version of Outlook Express. The title screen
reflects only major product versions, such as version 4 or 5.
Versions 5.01 and 5.5 are considered minor upgrades.
Active Scripting Enabled after Upgrade from Beta Versions of
Internet Explorer 5.5 Service Pack 2 and Internet Tools
-------------------------------------------------------------
If you are using a beta version of Internet Explorer 5.5 Service
Pack 2 and Internet Tools on Windows 2000, you may want to check
your security settings for the Restricted zone. "Active Scripting"
is disabled by default for this zone in the released version of
Internet Explorer 5.5 Service Pack 2 and Internet Tools. However,
beta users might find this setting enabled after installing the
released version.
To return this setting to its proper value in Internet Explorer 5.5,
use the following steps:
1. On the Tools menu, click Internet Options.
2. Click the Security tab, click Restricted Sites, and then click
Default Level.
=================
DEVELOPER'S NOTES
=================
New Language Features in JScript and VBScript
---------------------------------------------
Internet Explorer 5.5 Service Pack 2 ships with new versions of
Microsoft JScript(R) and Visual Basic(R) Scripting Edition (VBScript).
Documentation for the new features in Windows Script 5.5 can be
found on the Web at: http://msdn.microsoft.com/scripting/
You can read about the most important new features in JScript
and VBScript at the following Web site: http://msdn.microsoft.com/
workshop/languages/clinic/scripting121399.asp
The updated Windows Script engines will also be posted for
individual download from http://msdn.microsoft.com/scripting/
so they can be installed on computers that are not running
Internet Explorer 5.5 - for example, on an ASP Web server.
The Microsoft Office Developer Workflow Toolbar
-----------------------------------------------
In this release of Internet Explorer, the Microsoft Office
Developer Workflow Toolbar control will not data bind properly
on a Microsoft Access data page. This control was affected by a
fix in Internet Explorer 5.5, so an update of this control will be
necessary. For the latest updates, visit the following Web page:
http://microsoft.com/office/
Printing Controls
-----------------
The re-architecting of the print code in Internet Explorer 5.5
Service Pack 2 has exposed print bugs in several third-party
controls, causing some controls to print improperly and some
not to print at all. Although we have strived to maintain print
compatibility, we cannot ensure that all third parties will have
corrected these problems.
HTML Buttons with Unselectable Attribute
----------------------------------------
When the "unselectable" attribute in Internet Explorer 5.5 is applied
to buttons, the default onclick action (depressing the button)
doesn't take place. A simple workaround is to add a behavior to buttons
that causes this action. Add the following to the top of the file
containing the unselectable buttons (or to a CSS stylesheet that's
referenced from the file):
<STYLE> BUTTON { behavior:url("***.htc") } </STYLE>
(where *** is the name of the htc file that contains the behavior)
The htc file should contain the following:
<component>
<attach event="onmousedown" onevent="element.style.border=
'thin inset'">
<attach event="onmouseup" onevent="element.style.border=
'thin outset'">
</component>
=========================
APPLICATION COMPATIBILITY
=========================
Task Scheduler in Windows NT 4.0
--------------------------------
Windows NT 4.0 included an old version of the Schedule service,
also known as At service (Atsvc.exe). Internet Explorer 5.5
upgrades it to the new version of the Schedule service, named
Task Scheduler (MSTask.exe) and converts At jobs to Scheduled
Tasks.
With the old At service, all At jobs had to run in the same
account as the service itself. The default account for the
service was the Local System account, but it could be changed
to another user account as needed. Some Windows NT 4.0 users
changed the At service's account because they needed their jobs
to run in a user account.
With Task Scheduler, each scheduled task can be configured to
run in a different account. The Task Scheduler service itself
has to run in the Local System account.
For backward compatibility, Task Scheduler allows the user to
set one account to use when running scheduled tasks that were
created from At jobs. When Internet Explorer 5.5 is installed,
this account is set to the Local System account. If you are
running Windows NT 4.0 and you change the account that the At
service ran in to something other than the Local System account,
then after installing Internet Explorer 5.5 you need to manually
re-enter the user name and password for that account. To do this,
go to the Scheduled Tasks folder, click the Advanced menu, and
then click AT Service Account.
This must be done manually because Internet Explorer 5.5 Service
Pack 2 Setup cannot decrypt the password that was used by the
At service.
For more information about At service compatibility, see online
Help in Task Scheduler.
Selection in IFrames
--------------------
In Internet Explorer 5.0, if a user made a selection inside an
iframe and then clicked outside of the iframe, then in the
containing document, the selection inside the iframe would remain
selected. In Internet Explorer 5.5 Service Pack 2, the selection
in an iframe is cleared when the user clicks outside of it.
Assistive Technology and Accessibility
------------------------------------
Some changes in Internet Explorer 5.5 Service Pack 2 might affect
its compatibility with some accessibility aids. If you use an
assistive technology such as a screen reader or voice-input device,
please contact the manufacturer of the aid for compatibility
information.
