First of all, my question is not quite the same as
Is Office 2007 PIA deployment possible without Office 2007?
I am not looking to use the PIA's yet. The IT engineers would ideally like to deploy the 2007 PIA's to everyone's computers before they upgrade Office 2007. This way there is fewer things that have to go right all at once. I am wondering if this is possible
Yes, it's possible, we ended up doing it and it worked fine.
