I have a system that was out of space completely. I didn't think I had that many files (80GB hdd), but I finally found that over 50GB in use were in C:\Windows\Installer directory. I know these are dangerous to delete outright, but the utility that most forums seem to suggest is no longer available from the MS website.

Any other suggestions on how to overcome this?

The Windows Installer Cleanup utility was discontinued by Microsoft since it could damage other OS components and the like. It is still available to use at your own risk: http://majorgeeks.co...lity_d4459.html
After reading from a couple other forums after the installation you should:

After installation browse to C:\Program Files\Windows Installer Clean Up\ to find MsiZap.exe

Other people said that you should try running the program with the -G switch.

Before you try this program, I strongly advise that you perform a full system backup in case something goes wrong.
