XRL on a an "XP Virtual PC" within Windows 7 32-bit environment

trying to get 1.43 XRL working in this environment without much joy. It will install, but I get lots of errors (permissions, missing DLL's) when trying to create a basic Detailed Report.
It is part of a 2003 SBS system, and there are another 2 XRL users on the network (both on True XP).
Any help appreciated.
Gale.
