Have you read the thread that details how to get BlitzMax to work under Vista? I can't find the link right now, but it may answer all your questions.
Also, I've got BlitzMax installed in Program Files and have no problems at all. I do have UAC turned off though, and only turn it on to test final builds, etc.
