CAUSE

This error can occur if the Mscmouse.com driver by Mouse Systems is being loaded in the Autoexec.bat file, or if Gui.exe is being loaded from the "load=" line in the Win.ini file.

Back to the top

Remove the Mscmouse.com line in the Autoexec.bat file and then install the Mouse Systems driver update available from the Mouse Systems BBS.

Use any text editor (such as Notepad) to open the Win.ini file in the Windows folder and remove the Gui.exe entry from the "load=" line. Save the Win.ini file, close it, and then restart your computer.
