I am maintaining a bunch of computers with different versions of Office on (2007 upwards). I have the installation disks and so know the license keys, but I don't know which machine is using which one.

Is there a way of determining even just a part of the license key activated on each machine?

Office 2014 has an OPSS.VBS script that tells me the last few characters (using the /dstatus option), and that is excellent. However, the script isn't present on the older versions and it won't run on them if I copy it across.
