Using same key for all installs

[Matthew1985]

Hi. We have two different VLKs for office. One for office 2003 and a new one for office 2007 (we are using downgrade rights to use 2003).

What I was wondering is is it legal to use just one key on all installs or do we need to use one on half the PCs and the other key on the second half?

Thanks.

I think you've got slightly confused.

The Office 2007 product key will not be recognised by Office 2003, and vice versa, so you have no choice but to use the one key. But that's ok... that's what it is intended for, providing you have a license for every machine you use it on.
