Query: Not truly Windows XP (or Vista) compatible

Wouldn't install at all on Windows Vista. Product claims to be compatible with XP, but gave an error and exited. Search the web for "my amazing human body xp patch" to find a patch. Even with the patch, though, this is clearly very old software that is not truly XP compatible, as the term is used in industry. Publisher is selling very old goods; this hasn't been updated in 10 - 12 years. That's fine for a book, but not for software.
