When to Remove Internet Explorer 5

Remove Internet Explorer 5 before you perform any of the following actions:
  • Installing an earlier version of Internet Explorer (3.0, 3.01, 3.02, 4.0, 4.01 or 4.01 Service Pack 1).
  • Restoring a registry (System.dat or User.dat) that was created before you installed Internet Explorer 5 (this applies to Microsoft Windows 95 and Windows 98 only).
  • Using a Windows NT Emergency Recovery Disk (ERD) you created before you installed Internet Explorer 5 (this applies to Windows NT only).
  • Reinstalling your operating system (Windows 95 or Windows NT).
  • Installing or uninstalling operating system upgrades (for example, Windows 95 Service Pack 1).
  • Installing the Windows Desktop Update component from Internet Explorer 4.x (this applies to Windows 95 and Windows NT 4.0 only).
  • Repairing Internet Explorer 5 does not succeed or does not correct the problem.

Uninstalling Internet Explorer 5 May Not Be Supported

There are some configurations in which uninstalling Internet Explorer 5 does not work. Uninstalling Internet Explorer 5 is not supported in the following situations:
  • Internet Explorer 5 is installed in multiple operating system installations (Windows 95, Windows 95 OEM Service Release 2 or 2.5, Windows 98, or Windows NT 4.0) on the same logical hard disk. If you need to run Internet Explorer 5 in multiple operating systems, you must install each operating system on a separate logical drive.
  • You have removed the Internet Explorer 5 backup files or the backup files are no longer on the drive. If you removed the backup files or they cannot be located, you cannot uninstall Internet Explorer 5 without reinstalling Windows into a different folder.
