I do not think that uninstalling with an uninstaller would be that necessary. Forgot to mention that I have tried both the English and the International versions of 81.98, same thing - uninstall is busted. If someone knows how to resolve this issue, please give a hint. I have to go into a Safe Mode, revert to VGA driver, and use Driver Cleaner to get the job done. It throws the usual 'Nvudisp has caused an error in Nvudisp.exe and will now close' and cannot uninstall. While most of the driver versions install and uninstall without a hitch, 81.98 gives me headache every time I have to uninstall it. For the games part, I often have to rotate between different driver versions, going as far back as 30.82 and as recent as 81.98, which is the latest that officially support GeForce Ti 4200. Use these machines mostly for playing older video games, or using legacy productivity software. Video card in both is nVidia GeForce Ti 4200, AGP 2X/4X, 64MB RAM.

I have two retro machines running vanilla Windows 98SE US-English version.
