I've previously purchased and installed MS Office Enterprise 2007 on my
computer with its own 25 character product key. I'm attempting to download
and install a trial version of MS Project Standard 2007 and was given a
different 25 char key for that.

The trial literature refers to the trial as "MS Office" and I'm concerned
about overlaying my current Office installation or having it compromised as a
result of installing this Project trial.

Any comments about how MS manages this?
