Vista - uninstall.exe has stopped working

Hi,

I stupidly tried to install my Minolta 2300 DL drivers on a Vista machine
before actually checking out what drivers were compatible. I discovered from
the Konica Minolta web site, that I needed new drivers. When I try to
install the old drivers (for an NT machine per the manual ... predates XP I
think) I get a message that says this:

uninstall.exe has stopped working

A problem caused the program to stop working correctly. Windows will close
the program and notify you if a solution is available.

The only button is "Close Program"

So, now I can't get this printer driver uninstalled so I can install the
correct Vista version.

Any ideas and help on getting rid of these drivers would be extremely helpful.
