SYSTEM 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 á 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
SETUP
Before you install Internet Explorer 4.0, you should make sure that no scheduled tasks are running, because they might interfere with the Setup process.
CAUTION: 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.
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, the download directory will be removed. For information about removing the Setup files, see "Installing Internet Explorer 4.0."
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:
Click the Start button, and then click Run.
Type the following: regsvr32 rsabase.dl
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 if you don't follow these steps.
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:
In Control Panel, double-click the Add/Remove Programs icon.
Click Microsoft Internet Explorer 4.0, and then click Add/Remove.
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:
In Control Panel, double-click the Add/Remove Programs icon.
Click Microsoft Internet Explorer 4.0, and then click Add/Remove.
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.
