I get this error no matter what I try to do to fix it. I read what other people on the forum have done to eliminate this error but none of these methods work in my case. I tried setting disabling read-only on the folder and all sub-folders of the cd files (copied to my hard drive first), I tried changing the temp directory/resetting to default, I tried rebooting (many times), and deleting the two files in the system32/drivers folder. My computer has last updated with the Autopatcher up through June. I installed XP vanilla as a Virtual PC, installed SP2, and .NET 3.0. I copied the same cd folder I used and the same vlite folder and everything works fine. I'll make a copy of this Virtual PC image and see if installing windows updates breaks it.
