Change Office Installation Path?

[Coucher]

Here's the deal. Got about 140 systems that were part of a 1000+ system rollout. This is the problem. The system image for all 1000 systems was created at one site. So the Office install on all the systems point to that network share. For example \\Site1Server\OfficeXP\PROPLUS.MSI Now the 140 systems at this site, cannot hit the \\Site1Server. I need to change the original Office Installation Path on these machines to for example \\Site2Server\OfficeXP\PROPLUS.MSI where \\Site2Server is the local intallation point for this site. I've spent all day looking around the registry & net and have come up empty. Any clue??

Thanks in advance.

I found 4 registry keys on my pc for my office 2000 installation by searching for "data1.msi" in the registry.

I did this as well, searching for PROPLUS.MSI. However none of these are the Installation paths. They're all just listings of the last 5 or so MSI's run.
