I installed it without a problem. Here is what you need to do:
- Use wizard to Install Internet Explorer 7 normally in an XP bottle
- Then install Microsoft .NET Framework 1.1 in the same bottle
- Now install QuickBooks 2005.. if the CD does not work you can download it from the company and use your key:

I didn't test this thoroughly. I basically just started it up and created a business and then went to add a user and that was it. I don't know if printing, saving, etc. works.
