This happened with me updating from 0.6.0 to 0.6.1. I had attempted to open AS in admin mode with every other application closed but the update still failed for me. I also tried deleting the Temp folder.

Eventually I noticed in the task manager when everything was closed I still had a sizeable java.exe still running in the background for some reason.

What I did was open AS in admin mode, run the update and let it fail, claiming a file is locked / access is denied or something similar. Open the task manager and I noticed 2 java.exe processes running. For me the smaller one (about 200k) was the AS updater utility itself. But if I killed the larger one (about 600k), and hit retry, the update went through without issue.
