Windows Virtual Machine Doesn't Start

Question

I recently installed a clean install of windows 7 pro 64-bit. I installed windows XP mode as described on the microsoft website followed by the update provided but when I try to open windows virtual PC nothing happens. I click on the program icon and nothing happens. When I try to open windows XP mode I get the error message "Cannot start Windows Virtual PC Host Process. Check the System event log for more detials. Server execution failed" Once I check the event log there is nothing there. The PC I am running on supports hardware virtualization and it is enabled in the bios. My coworker just installed windows XP mode on the machine right next to mine and it works fine. Can someone please tell me how to get this thing to work. Running virtual 2007 is not an option. 

Answer 1

Same problem.
In past i've used successful windows virtual pc, but now it won't work.
I tryed uninstallind the Windows6.1-KB958559-x64.msu update and the windows xp mode and deleting the old virtual machines.
After reinstall the Windows6.1-KB958559-x64.msu update the problem returns as before.
I get this error: "Cannot start Windows Virtual PC Host Process. Check the System event log for more detials. Server execution failed"
Looking at the event viewer into "Applications and Services Logs/Microsoft/Windows/Virtual PC/Admin" i find "Virtual machine ''. Error - Server execution failed"
 (0x80080005)" and just before this message i get "One or more files from the Virtual PC installation are missing. Please reinstall Virtual PC and try again."
So i tryed a lot of times uninstalling and reinstalling, unsucessfully. What i can do?
