O 2003 nothing like 07 or 10
My copy of Office 2003 has been passed around like a $10 H--ker. It probably has 50 installs on the one activation key. Never has anyone ever reported it didn't work, was deactivated, etc. This won't fly on O 2007, O 2010. But 2003, if you have the discs and the original key, you're fine.
