Errors using an Avid xpress 3 and solutions

In trying out the Avid Xpress 3, this new version is quite difficult to please. For one It does not install on some computers that does not have avid on it and I get errors when I try to run it on one computer that has Windows XP installed in it and there are more errors when trying it out on XP. What are ways and means for it to run in an XP? Or should I settle on a lower version of Windows OS which can be disappointing.
