The information in this article applies to:


 * Microsoft Windows 95

-

SYMPTOMS
When you restart your computer after installing Windows 95 or making a system change that requires the computer to be restarted, you may receive the following error message:

While Initializing Device IOS: Windows Protection Error

Or, you may receive a general protection (GP) fault error message in Gui.exe.

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.

RESOLUTION
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.
