hi,
I got office 2007 Home and Student edition, and have yet to install it on my 5 pc's.
My question is, how many times can you install Office 2007???
It says on the back that it can be installed on only 3 pc's, but this might not be the case for whatever reason.

any help appriciated

Uhm. Why would you not be limited by the number of installations specified in your license agreement?

It's three computers for the retail version and one specific device for the OEM version of Office H&S 2007, period.
