Some years ago I bought and installed MS Office Small Business Edition 2003, which included Publisher 2003. Later, we got a new computer and as part of the purchase I had them install MS Office Home Edition 2007, which DID NOT include Publisher 2007. I still have the original CDs for 2003, and many times I wish I had Publisher. Can I install Publisher 2003 on the machine with Office 2007? If so, how? Appreciate any advice received...
