I'm trying to install the Microsoft Office 2007 Compatibility patch on ~ approx. 250 PCs (College situation). I've installed it on 20 PCs so far, and 2 of them have come up with a very terse error saying the install failed. This happened right after the big tan 'terms and conditions' screen. I've tried installing from a local copy (on thumb drive), over the net from a college website, and from Microsoft's site - all with the same error. I'll keep digging, but I'm fairly sure neither has an older version of the patch on it as neither could open a .docx or .xlsx test file. Any help would certainly be appreciated. TJOzzie
