Anyone ever tried launching QTP on Virtual PC (7.01)?

I am trying out the QTP 8.01 demo (available from the Mercury web page) and all I get is a splash screen, then nothing. It works fine on a real PC, but for convenience it would be nice to play w/ it away from work in VPC on my powerbook.

Haven't been able to find anything re: this in these forums or on Mercury's Knowledge Base.

Any help would be appreciated.
