IMPORTANT: This article contains information about editing the registry. Before you edit the registry, you should first make a backup copy of the registry files (System.dat and User.dat). Both are hidden files in the Windows folder.

SYMPTOMS

When you start Windows 95, you may receive the following error message:
Cannot find a device file that may be needed to run Windows or a Windows application.

If you deleted this file on purpose, try uninstalling the associated application using its uninstall program or setup program.

If you still want to use the application associated with this device file, try reinstalling that application to replace the missing file.
