I've got a Powerbook G4 12" which I've installed MS Virtual PC on. I've installed a proper version of Windows XP Professional, fully patched and licenced and now I want to run an application which is on a CDROM provided by a training company. The application runs fine on a PC and is shockwave based. On the Mac however, although everything seems to run fine under VPC, the application crashes with an access violation (0xC0000005) error stating that "run.exe" encountered a problem. I've installed the latest shockwaver version (and previous ones) with no luck so far and in all instances, Shockwave runs fine on the Adobe test page.
