I'm trying to uninstall Microsoft Virtual PC 2007 from my Windows 7 machine. Logged in as administrator, when I attempt to uninstall I get a messagebox stating

"The system administrator has set policies to prevent this installation."

Excuse me? No I haven't.

Immediately following, another messagebox displays:

"You do not have sufficient access to uninstall Microsoft Virtual PC 2007. Please contact your system administrator."

I didn't do anything unusual when installing or setting up the software. Just normal home use computer.

Any ideas on how to remove this software?


The Virtual PC may be holding some resources that prevents the uninstall. Reboot into Safe Mode and try the uninstall again.

This page describes how to boot into safe mode.


In my experience with Virtual Server, this happens when Application Information service gets someway stuck or stopped.

Rebooting is enough to fix it.
