unable to install new programs

[Guest]

for some reason, since I have uninstalled the driver for my video adapter, I
am now unable to run most .exe files that install programs on my computer.
When I try I get an error message that includes the location of the file.
The message says "The system could not find the environment option that was
entered." I would really appreciate any help with this problem.

Thanks

What steps did you take to end up in this situation?
Why did you uninstall the video adapter?
Have you tried reinstalling it?
