If you still have the same message onscreen...
Look for one of the CTRL keys, hold it down and while holding it down press C to return to windows 3.1

Shut down windows 3.1 and restart the computer and windows.

To try to load a driver for use under windows 3.1, get to the main group you were in before and perform the steps you did before using the Windows setup icon. Select a mouse from the list this time instead of selecting "other mouse"
Try the choice for Microsoft, PS/2 mouse for example.
You may be asked for one of the windows 3.1 original installation diskettes.

If you have a mouse which windows 3.1 does not supply a driver for, the diskette which came with the mouse is needed and then it would be appropritate to select "other mouse" and put in the diskette.


Here's some more info on the error.
"Windows Setup
Setup cannot find OEMSETUP.INF
Please type a new path to the OEMSETUP.INF file. OK"

The Windows 3.1 setup program was begun after Windows was previously installed.

The setup program icon in the MAIN group was selected. The "change system settings" entry from the options menu was selected and a search for an alternate manufacturer's mouse driver
was made. The setup program looked for the file on a diskette. The diskette inserted did not contain the OEMSETUP.INF file. The file is needed for windows to load the mouse driver.
On my computer the mouse choice for Microsoft, or IBM PS/2 works fine.
