Install Virtual PC2007 SP1 on Windows 7

Today morning I want to install Virtual PC 2007 sp1 on my Windows 7, but I run this error message

 

I went to Windows 7 compatibility site to check if Virtual PC is compatible with Windows7, and the result is Virtual PC 2007 SP1 is compatible with Windows 7. Then I googled the solution and found this issue site .

That is because I formerly installed an update name Windows Virtual PC. Only when I get this update uninstalled can I install the Virtual PC 2007 SP1.
