I'm having the same issue. I installed Office 2k7 last week, and the computers are still showing in a collection of computers without office 2k7. It shows when I look at resource explorer, but not in any query to prove I've done my job.
Is there any way to force the software inventory? Right click tools doesn't do much. Does anyone know what the actual command is to force the software inventory on the client? Maybe I can do a psexec type thing.
Thanks
