EASER I have discovered that it is, but only in a very convoluted way. I have to open MS Word and choose "look for updates" through that program. It then opens the auto update program and find the update. However, it then won't let me install the update until I first quit MS Word. I also found with Office 2008 that between the first install and the most recent update, I now have 88 - yes, 88 - receipts just for Office in my Library/Receipts folder. Truly remarkable.
