Mike:
Thanks for you suggestions. I made the mistake back in September of upgrading to SP3 ad it's been downhill ever since. I had so many issues after the upgrade that my old PC was just about usless,had to boot in safe mode ever since. That's why I bought a new PC with SP2. I do disk cleanup just about every two weeks. It's not the install that I have a problem with, the install goes fine. It's when I try to run PPV2007 that I get the message that it needs XP to run and I'm running XP. I have disabled my virus protection (McAfee). For some reason I have a feeling that it's an update that I received back in September that caused the problem. It was working just fine up until then. The puzzle is whey doesn't PPV2007 recgonize that I have XP on my machine.
Thanks again,
