SYMPTOMS
When you start Outlook Express 4.0 after uninstalling Internet Explorer 5, you may receive the following error message:

Unable to start the program. One of the required components maybe busy or missing. Please check your installation and try again.

Uninstalling and reinstalling Outlook Express 4.0 does not solve the problem.



CAUSE
This behavior can occur if the Outlook Express 5 version of Inetcomm.dll is still in the Windows\System folder.



RESOLUTION
To resolve this issue, use the System File Checker tool to extract a new copy of the Inetcomm.dll file from the Windows 98 CD-ROM to the Windows\System folder.
