Windows 7 Virtual PC 2007 problem

Hello,

I installed the Windows 7 RC as a fresh install.
I also used the beta version and upgraded it 4 times.

Everything was installed and worked, but now i have a problem with virtual pc.

I installed the XP mode to try it, but my laptop doesn't have hardware virtualisation, so the XP mode doesn't work.
Before i installed the XP mode, virtual pc was working as normally, but when it was installed, virtual pc didn't work anymore.

Now i removed both, the XP mode and virtual pc 2007.

Now i get this error even before the install
Link Removed due to 404 Error

I already tryed to disable the program compatibility assistant using group policy, but that didn't work.
There are also for some reason no restore points from before installing the XP mode:

Link Removed due to 404 Error

How can i install and use virtual pc again without doing a reinstall??

Problem is solved!

You also need to uninstall the update.
This is not listed in the programs, but at the installed update view.
I remove the update and now i can use virtual pc again.
