Hi guys,

I am trying to install Virtual PC on a Win 8.1 laptop. Downloaded the file straight from Microsoft, but when I attempt to run it, I get an error:

Windows Update Standalone Installer
Installer encountered error: 0x80096002
The certificate for the signer of the message is invalid or not found.

I have re-downloaded the file with the same success. If it matters, the Windows Update Agent version is 7.9.9600.17336

Any help would be greatly appreciated!
