Is Micrsoft 2003 compatible with Windows 7. Also, just purchased a new computer with Windows 8, I can't get it to upload to 8 so assume that is a no go? Is Microsoft 2007 compatible on Windows 8 or do I have to go to 2010? If I purchase the Microsoft 2010 from you, how many times can that be installed on my computers? I have 3, and I need the office version with outlook, excel, word, etc
