Did you get an answer on this? We have a similar problem. Admins and staff can access the program no problem. A student logon produces a message saying the installation is corrupt.... re-install from original source blah blah. It used to work for all users, but I don't know when it stopped working. This issue is replicated throughout the school network. I have tried clean install of OS and program with the same results. I feel it is a folder permission, but I can't nail it down. The students are on mandatory profiles and user GPOs so it could be in here. All PCs are Win7x64, and I get the same result no matter how the software is deployed (.msi via AD, .msi via zenworks, or manually from file). Has anyone got any ideas?
