>Some clients who are running Windows 2000, after upgrading to our VFP8 application, cannot get into the program and get C005 errors when clicking on the desktop icon. The VFP7 version worked fine and the VFP8 version works on other machines. What is different about Windows 2000?
Elyse,

The problem occurs on certain Windows 2000 PC's that have (or have had) roaming profiles when the profiles have been used on WIN XP machines. If you remove the profile and create a new one, the problem will be gone.

Slightly less radical, if you find a ntuser.dat file in the user profile and delete it, il will be recreated the next time you log on with this profile. The problem will also be gone.

Check also Thread #048494.

And do some google research on "Daniel Boss" from Switzerland in newsgroups, he also has a clear understanding of what is happening.
