SYSTEM REQUIREMENTS
===================

To run Internet Explorer 4.0, your system must meet the following 
minimum requirements:

- A 486 with a 66 Mhz processor (Pentium processor recommended)
- For Microsoft Windows 95:
  8 MB of RAM minimum, 16 MB with Active Desktop
  For Microsoft Windows NT:
  16 MB of RAM minimum, 24 MB with Active Desktop
- For Microsoft Windows NT: 
  You must be running Service Pack 3 (or higher)
- 40 to 70 MB of hard-disk space (depending on installation type) 
- Mouse
- Modem
- CD-ROM

Using Internet Explorer 4.0 with Virtual Memory
-----------------------------------------------
Internet Explorer requires you to use virtual memory in order to 
run properly. To make sure you are using virtual memory:

1. Click the Start button, point to Settings, and then click 
   Control Panel.

2. Double-click the System icon, and then click the Performance tab.

3. Click Virtual Memory.

4. If you are specifying virtual memory settings, clear the 
   Disable Virtual Memory check box. If this check box is selected, 
   Internet Explorer will not run.

   TIP: You can set Windows to manage virtual memory for you by 
        selecting the Let Windows Manage My Virtual Memory check 
        box.


SETUP
=====

- WARNING: Do not install any previous version of Internet 
  Explorer over Internet Explorer 4.0. If you need to install 
  an earlier version of Internet Explorer, you must uninstall 
  Internet Explorer 4.0 first.

- You should always uninstall your current version of Internet 
  Explorer 4.0 before installing a newer build.

- It is recommended that you download Internet Explorer 4.0 to a 
  directory that does not contain any other files and that will not 
  be used for any other purpose. If for some reason you want to 
  uninstall the setup files by clicking the Add/Remove Programs 
  icon and then clicking Microsoft Internet Explorer 4.0 Setup 
  Files, the download directory will be removed.

- Before you install Internet Explorer 4.0, you should disable any 
  scheduled tasks from running that might interfere with the Setup 
  process.

Installing Internet Explorer 4.0
--------------------------------
Whether you choose to install over the network or to download 
the installation files to your hard disk, the Setup files are 
copied to your hard disk. This is so you can reinstall more 
quickly if you need to. If you want to reclaim the disk space, 
you can remove the setup directory by double-clicking the Add/Remove 
Programs icon in Control Panel and then clicking Internet Explorer 
4.0 Setup Files.

You cannot install Internet Explorer 4.0 to or run it from a 
network drive. However, you can download it to a network drive. 
To do this, you must map the network drive to a drive letter on 
your computer. You cannot download Internet Explorer 4.0 to a 
UNC path.

If Internet Explorer 4.0 appears to stop responding at the end 
of Setup, you need to restart your computer manually. 

Running Internet Explorer 4.0 on Windows NT
-------------------------------------------
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 
4.0. This is also true for some add-on components.

If you're running Internet Explorer 4.0 on Windows NT, you must 
set user permissions to Full Control for the Temporary Internet 
Files folder (cache). The user must have write permission in order 
for files to 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 4.0, 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.dl
3. Click OK.

Running Internet Explorer 4.0 on a Dual-Boot Operating System
-------------------------------------------------------------
If your computer is set up to dual boot between two operating 
systems, you must install Internet Explorer 4.0 in separate 
directories for each operating system. For example, if you are 
running Windows 95 and Windows NT, you might want to install 
Internet Explorer 4.0 in C:\IE95 for Windows 95 and in C:\IENT 
for Windows NT. Do not try to use the same installation of 
Internet Explorer with two operating systems. If you later 
uninstall Internet Explorer 4.0, one of your operating systems 
may be left unbootable.

Note also that if you dual boot between two operating systems 
that are configured to share a Program Files folder, and you 
uninstall an add-on component from one of your Internet Explorer 
4.0 installations, it will be removed from both of them. This is 
because the add-on files are stored in the Program Files folder.

Uninstalling Internet Explorer 4.0
----------------------------------
You can uninstall Internet Explorer 4.0 by carrying out the 
following steps:

1. In Control Panel, click the Add/Remove Programs icon.
2. Click Microsoft Internet Explorer 4.0, and then click Add/Remove.
3. Follow the instructions on your screen.

Cannot Use Registry or ERD Files Created Before 
  Installing Internet Explorer 4.0
-----------------------------------------------
If you install Internet Explorer 4.0 and then restore a Windows 95 
registry that was created before you installed Internet Explorer 4.0, 
or use a Windows NT Emergency Repair Disk (ERD) that was created 
before you installed Internet Explorer 4.0, you may be unable to 
start Windows 95 or Windows NT 4.0.

To resolve this problem, use the Ieremove.exe tool to remove Internet 
Explorer 4.0. For information about how to do so, open the Microsoft 
Knowledge Base at http://www.microsoft.com/kb/default.asp, and then 
see the following articles:

  For Windows 95, see Article Q166313, 
  "Removing Internet Explorer 4.0 for Windows 95 Using Ieremove.exe"

  For Windows NT, see Article Q166314,
  "Removing Internet Explorer for Windows NT 4.0 Using Ieremove.exe"

Adding or Removing the Windows Desktop Update
---------------------------------------------
To add or remove the Windows Desktop Update, carry out the following 
steps:

1. In Control Panel, double-click the Add/Remove Programs icon.
2. Click Microsoft Internet Explorer 4.0, and then click Add/Remove.
3. To remove it, click "Remove the Windows Desktop Update component 
   but keep the Internet Explorer 4.0 Web browser."

   To add it, click "Add the Windows Desktop Update component from 
   Web site," and then follow the instructions on the screen.

NOTE: For this release, clicking "Add the Windows Desktop Update 
component from Web Site" opens the Internet Explorer 4.0 components 
download page so you can download and install the Windows Desktop 
Update. If you have previously downloaded or installed the Windows 
Desktop Update, you can enable it without connecting to the Internet 
by running IE4setup.exe from your local Internet Explorer 4.0 Setup 
folder. When prompted, click Yes to enable the Windows Desktop 
Update, and then choose to upgrade only newer items.

Installing Internet Explorer in a Language Different 
  from the Operating System Language
----------------------------------------------------
If you install a version of Internet Explorer in a language 
different from the language of the operating system you are 
running, the Windows Desktop Update will not be installed.


USING A LOCAL AREA NETWORK PROXY SERVER OR FIREWALL
===================================================

If your local area network or ISP uses a proxy serveror firewall 
to protect your network from being accessed by other people on the 
Internet, carry out the following steps, which set up your computer 
to gain access to the Internet through a firewall:

1. Run the Internet Connection Wizard:

   - Click the Start button, point to Programs, point to Internet 
     Explorer, and then click Connection Wizard.

2. Configure your computer to connect to the Internet by using 
   the TCP/IP protocol on your local area network. 

3. When you are prompted for the gateway address, type the IP 
   address (for example, 123.456.789.123) supplied by your 
   network administrator only if your organization uses gateways 
   for routing information over the network.

   NOTE: The gateway computer is not the same as the proxy or 
         firewall computer that protects your local area network 
         from the Internet, so do not type your proxy or firewall 
         address here.

4. Click the Start button, point to Settings, and then click 
   Control Panel.

5. Double-click the Internet icon, and then click the Connection 
   tab.

6. In the Proxy area, select the Connect To The Internet Through 
   A Proxy Server check box.

7. Click Change Proxy Settings.

8. In the first text box, type the HTTP server address for the 
   computer you want to use as the proxy server. In the second text 
   box, type the port number. The following is an example of a proxy 
   server and port number:

   http://myproxy.mycompany.com:80

   In this example, you would type http://myproxy.mycompany.com in
   the first text box, and 80 in the second text box.

   You can use a different proxy server for different types of 
   addresses. However, if you want to use the same proxy for all 
   types of addresses, make sure you select the Use Same Proxy Server 
   For All Addresses check box.

9. In the Exceptions area, click in the text box, and then type the 
   names of the computers, domains, and ports on the Internet that,
   when accessed, will not go through the proxy server. Separate each 
   item you type with a semicolon (;). If you do not know what to type 
   here, see your network administrator.

   If you do not want to use the proxy server for local addresses, make 
   sure you select the Do Not Use Proxy For Local (Intranet) Addresses 
   check box. Local addresses are defined as those where the server 
   name does not contain a period (.). For example:

   http://internalweb/        is a local address.
   http://www.microsoft.com/  is not a local address.

   For Help on these items, click the ? in the title bar, and then 
   click the item.

10. When you have finished changing settings, click OK.

11. Click OK again to close Internet properties.
    If you are running Internet Explorer, you need to restart 
    your computer so that the new proxy settings can take effect.

Using the Novell NetWare 32-bit Client
--------------------------------------
If you are using the Novell NetWare 32-bit client with Windows 95, 
add the following registry entry to your system:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings
	DontUseDNSLoadBalancing = (REG_DWORD) 1

This setting will ensure correct usage of proxy servers with 
Internet Explorer on your network. This will be fixed in future 
updates.

Using Internet Explorer with Socks Proxy Servers
------------------------------------------------
If you are setting up Internet Explorer with a Socks proxy server, 
you must set it up separately from other proxy information (for 
example, HTTP, FTP, or Gopher). In most cases, this means that all 
other proxy fields should be left blank and the Socks field should 
contain the address of your Socks proxy server. The only exception 
is when you are using a Socks proxy and a different proxy (for example, 
HTTP) on the same connection. If you are having trouble, please contact 
your network administrator for information about Socks and proxy servers.


HTML DEVELOPERS
===============

Structuring HTML with Framesets
-------------------------------
If you are designing pages with framesets, you must use the 
following HTML structure for the pages to work correctly in 
Internet Explorer 4.0:

- A <BODY> tag (or other text or tags that force a BODY) should 
  not appear before a <FRAMESET> tag. If a BODY tag does precede 
  the FRAMESET, the contents of the FRAMESET are discarded and the 
  page will appear blank.

- <SCRIPT> and <OBJECT> tags in a page with a <FRAMESET> tag must 
  appear in the <HEAD> section of the page.

Using the HTML Layout Control
-----------------------------
Some differences may be experienced when using the HTML layout control with IE4.0. For more information please see http://www.microsoft.com/workshop/author/layout

ActiveX Controls in Internet Explorer 4.0
-----------------------------------------
Because of some architectural changes in Internet Explorer 4.0 that 
were needed to support a wider range of controls more efficiently, 
some ActiveX Controls may not perform exactly as they did in 
Internet Explorer 3.0. A common cause of this is that the control 
was not created as Apartment Model Aware. Many control vendors now 
offer updated controls that work properly with Internet Explorer 4.0. 
If you have any problems with ActiveX Control support in Internet 
Explorer 4.0, contact the control vendor to see if an updated 
version of the control is available that fixes the problem.

Problem With Visual Basic 5.0 ActiveX Controls
---------------------------------------------- 
Some ActiveX Controls created with Microsoft Visual Basic 5.0 may 
not function properly in Internet Explorer 4.0, because these controls 
are not Apartment Model Aware. Controls that are created with VB 5.0 
should be rebuilt using the Service Pack available free from Microsoft 
for VB 5.0 and the Control Creation edition of VB 5.0 that allows for 
the creation of Apartment Model Aware Controls.


JAVA DEVELOPERS
===============

Installing Java Classes
-----------------------
As part of the VM for Java installation, the new class files are 
added to the class path of developer machines. If you install a Java 
development tool after installing Internet Explorer 4.0, please 
run the clspack tool in your Windows directory to put the classes 
on your class path. To create a single Classes.zip file in your 
%WINDIR%\Java\Classes directory that contains all classes stored in 
the package manager, use the following syntax: clspack -auto. This 
option also adds Classes.zip to the CLASSPATH registry key. 

Refreshing Java Applets Under Development 
  without Restarting Internet Explorer
-----------------------------------------
Microsoft Visual J++ 1.1 and other development environments have 
previously required the browser to be restarted in order for updated 
classes to be used while debugging. This was because of issues with 
Internet Explorer loading Java classes from the cache rather than from 
any updated classes on the developer's computer. Using Internet Explorer 
4.0, you can just press CTRL+F5 or CTRL + the Refresh button to 
cause the classes to be reloaded and any updates used.

Using Visual J++ with Internet Explorer 4.0
-------------------------------------------
If you use Visual J++, you can install Internet Explorer with or 
without the Windows Desktop Update. If you do choose to install the 
Windows Desktop Update with the browser, you will need to do the 
following:

1. Install Visual Studio SP2.
2. Modify your project settings as follows:
   a. On the Project menu, click Settings.
   b. Click the Debug tab.
   c. In the Category box, click Browser.
   d. Add the -new switch to the path to the browser. For example:

      C:\Program Files\Internet Explorer\Iexplore.exe -new

Note that this modification must be made on a per-project basis. 
For more information, see Microsoft Knowledge Base article Q167998.


NOTE TO FRENCH USERS OF INTERNET EXPLORER 4.0
=============================================

In order to comply with French laws on the use of encryption material, 
the following features have been disabled for users in France:

- S/MIME support in Outlook Express
- The Microsoft Wallet secure storage feature
- PCT 1.0 support

However, SSL 2.0 and SSL 3.0 support are authorized, and are still 
enabled.

KNOWN ISSUES
============

PICS Support Works Differently in Internet Explorer 4.0
-------------------------------------------------------
The Internet Explorer Content Advisor uses PICS (Platform for 
Internet Content Selection) ratings. The PICS functionality 
varies from that in Internet Explorer 3.0 in the following 
instances:

- The PICS rating is not used for documents using the file:// 
  protocol.

- If you have ratings enabled, you might not be able to view 
  certain items that you've added to your Active Desktop. If 
  you see a "Navigation Canceled" error message instead of Web 
  content, try turning off ratings. 

Some Programs Do Not Detect Browser Version Correctly
-----------------------------------------------------
Some third-party Internet-based programs use non-standard 
methods of detecting the current browser version. If you see this 
problem in a program you are running, please contact the program 
vendor for an update.

Temporary Internet Files Are Replicated 
  to the Home Directory of Roaming Users
----------------------------------------
The Temporary Internet Files folder is replicated to the home 
directory of users with roaming profiles. If you are running 
Internet Explorer 4.0 on a Windows NT system, this may cause 
disk-space problems on servers with numerous roaming users or 
with several users who have with large caches. To set cache size, 
click the View menu, click Internet Options, and then click the 
Settings button.

Java Applets Will Not Print on Asian Windows 95 Computers
---------------------------------------------------------
If you are running a Far East version of Windows 95, printing a page 
that contains a Java applet prints only the page without the applet. 
This will be fixed in a future release.

Using NetMeeting When Internet Explorer 4.0 Is in Offline Mode
--------------------------------------------------------------
If you start NetMeeting with Internet Explorer 4.0 in Offline 
mode, NetMeeting will not start properly, although no error 
message appears. To work around this problem, dial up using RAS 
for Windows NT computers or Dial-Up Networking for Windows 95 
computers. Or, in Internet Explorer, click the File menu, and 
then click Work Offline to clear the check mark.

Access Aptiva Issues with Internet Explorer 4.0
-----------------------------------------------
The Access Aptiva component of the IBM Aptiva PC does not render 
properly with Internet Explorer 4.0. To get an updated version of 
the Access Aptiva program, you can either go to the IBM home page 
at http://www.us.pc.ibm.com/aptiva, or click IBM Update Connector 
from the Start menu, which automatically downloads the updated 
components.


APPLICATION COMPATIBILITY
=========================

Adobe Acrobat: Using Internet Explorer 4.0 with 
Adobe Acrobat Reader 3.0
-----------------------------------------------
Using the Adobe Acrobat .pdf viewer in Internet Explorer 4.0 
may not work. You can download the latest version from 
http://www.adobe.com.

Also, if Content Advisor is turned on in Internet Explorer 4.0, 
you cannot view .pdf files in the browser.

CleanSweep: Critical System Files Replaced
------------------------------------------
If you are already running Internet Explorer 4.0, installing 
CleanSweep 3.0 is not recommended. CleanSweep replaces vital 
system files and will cause both Internet Explorer and the 
Active Desktop not to work properly.

DEC ClientWorks: Remove Xdmisrv.exe Before Installing 
  Internet Explorer 4.0
-----------------------------------------------------
If you are running DEC Client Works on a computer with Windows 95 
and with no networking services installed, you should remove the 
file Xdmisrv.exe from your startup group before installing Internet 
Explorer 4.0. Otherwise, you may see the following error message when 
your computer restarts after installation: "RPCSS caused an invalid 
page fault in module OLE32 at 015F:7FFBAD35." This error does not 
occur if any networking services are installed, including Dial-Up 
Networking. This issue has been fixed in DCOM95 1.1, which you can 
download from http://www.microsoft.com/com/.

Internet Information Server 4.0: Unable to Install from the Internet
--------------------------------------------------------------------
If you are installing IIS 4.0 beta 2 from the Internet on a computer 
running Internet Explorer 4.0, a dialog box will appear saying "Setup 
was unable to download information about available installation sites." 
To work around this problem, you can order the CD version from 
http://www.microsoft.com/iis while supplies last. You should not 
encounter this problem if you are installing IIS 4.0 from a CD.

Microsoft Money: Online Banking Does Not Work
---------------------------------------------
If you install Microsoft Money 97 on a computer running Internet 
Explorer 4.0, online transactions will not work. This is because 
Microsoft Money is using an older version of the file Schannel.dll. 
To work around this problem, go to the following Web site: 

     http://www.microsoft.com/ie/ie40/download/128bit.htm

Then install the 128-bit extensions from the Web to enable secure 
transactions.

Norton Utilities and Norton Navigator
-------------------------------------
- Norton Utilities version 2.0 is not compatible with the Internet 
  Explorer 4.0 Recycle Bin because of new features that have been 
  added to Internet Explorer.

- If you are running Norton Navigator, note that the Control Panel 
  shortcuts on the Start menu do not work.

- If you reposition the taskbar to the left or right side of your 
  desktop, the Norton Navigator quick launch area disappears.

- If you are running Norton Navigator, you need to disable the 
  Norton Taskbar feature in order to use the functionality of 
  the new Internet Explorer 4.0 taskbar.

For more information about Norton Utilities, see their Web site at 
http://www.symantec.com/nu/.
  
Procomm Plus 95 Web Browser: Browser Properties Control Doesn't Work
--------------------------------------------------------------------
In the Procomm Plus 95 Web browser, the Browser Properties control on 
the Setup menu does not work. However, you can set browser properties 
by double-clicking the Internet icon in the Windows Control Panel. 
Property settings for the Internet Explorer 4.0 browser will also 
apply to the Procomm browser.

Stacker: Size of Host Drive Must Be Increased
---------------------------------------------
If you run Stacker 4.1 on a computer with Internet Explorer 
4.0, you must increase the size of the host drive. If you do 
not increase the size of the host drive, you will not be able 
to restart your computer successfully. 

Telcom Fax: Unable to Send Network Faxes
----------------------------------------
This product currently does not work with Internet Explorer 4.0. 
For information about Telcom Fax 4.0, which is compatible with 
Internet Explorer 4.0, contact the manufacturer (http://www.ltc.com).
