Can I install Microsoft Office 2003 on multiple computers at home, if I own all of them?

You can install Microsoft Office on up to three computers if ... 1) they are all owned by the same person who purchased the license for MS Office, 2) they are used for personal use (i.e. you're not directly trying to profit from the use of the software), and 3) you input the original license key on all three computers.

If you do not follow all three of these criteria, then you are in violation of the licensing agreement and could be sued accordingly (although highly unlikely). If you are really in doubt about meeting any of the three conditions for legal use you should buy a new license for each computer (its cheaper than buying a whole new software package). To do so you would need to contact Microsoft and pay the applicable fee.
No, it is a violation of the license and copyright infringement.


Answer:
I think you can when I bought it I remeber reading that you could install it on up to 3 computers in your home.
