Run program in virtual machine

I am using VixVM_RunProgramInGuest to run a executable in a guest virtual machine. If the EXE requires elevation, it fails with the VIX_E_PROGRAM_NOT_STARTED error code. It works fine if the exe is not elevated.

I cannot figure out how to make this work.

I am using VIX API 1.12 and the guest OS is Windows 8.

LATER EDIT: Same problem on Windows 7. UAC is turned of on both machines.

Thanks
