I'm trying to get our corporate Office 2010 installer fully patched via dropping .MSP files in the \Updates folder and am running into a peculiar problem - updates seem to conflict with each other and undo one another's application.
For example, if I drop SP2's extracted .MSP files in the \Updates folder and install Office, I can then run Windows Update and get a list of patches for Office 2010 that doesn't include SP2. Great, makes sense, I pre-installed it via the Updates folder.
However, when I drop the MSP files from another patch into the folder, even if I rename them so as not to overwrite like-named files from the SP2 application, when I run Windows Update it shows SP2 as an available installation. It's a reduced filesize, but it's still there. This suggests to me that some component of SP2 is no longer installing once other updates are added to the folder.
Complicating matters further, re-integrating SP2 then undoes some of the other patches and they show up in the WU update list.
Has anyone had success in getting a fully-patched installation of Office made using offline patching, such that a "Check for Updates" operation will yield no missing patches? How did you do it?
