If you install Windows 95 Service Pack 1 on a computer with Internet Explorer 4.0 installed and then remove Service Pack 1, you may not be able to start Windows 95 after you reboot the computer.


Uninstalling Service Pack 1 replaces the Shell32.dll and Ole32.dll files with the original Windows 95 versions. The Windows 95 versions of these files do not work with Internet Explorer 4.0


Replace the Shell32.dll and Ole32.dll files with the Internet Explorer 4.0 versions. To do so, use the following steps.

NOTE: In the following commands, Windows refers to the folder in which Windows 95 is installed. Intern~1.0se refers to the folder in which the Internet Explorer 4.0 Setup files are located. If your folder names are different, adjust these instructions accordingly.

  1. Restart your computer. When you see the "Starting Windows 95" message, press the F8 key, and then choose Command Prompt Only from the Startup menu.
  2. At the command prompt, type the following commands, pressing ENTER after each command :

          cd \windows\system
          ren shell32.dll shell32.old
          ren ole32.dll ole32.old
          cd \intern~1.0se
          extract /e /l c:\windows\system shell32.dll
          md c:\temp
          extract /e /l c:\temp
          cd temp
          extract /e /l c:\windows\system ole32.dll
  3. Restart your computer normally.


Internet Explorer 4.0 installs newer versions of the Shell32.dll and Ole32.dll files, making use of the updates provided by Service Pack 1. Reinstallation of Service Pack 1 is unnecessary when Internet Explorer 4.0 is installed.
