I had the problem where it could not finish either, eventually after some timeout, a the dialog popped up the one saying it could not finish, I clicked on the dialog and was able to see that my firewall was preventing the automatic tools and such from running. Have you checked to see if some dialog in windows is waiting for input? It took a long time before the timeout happened. Not sure how long, but I was able to take out the trash, walk the dog and check email. When that was done, I still was waiting.
