I had TiVo Desktop installed and running fine. After a refresh of my Win 8.1 system, I needed to reinstall TiVo Desktop. The install fails at every attempt with "The installation ended prematurely because an error occurred". Yeah, not too helpful of an error message. Anyway, I looked up solutions to try at the TiVo support site and found only the "TiVo installation cleaner utility", and I have run the "Register VBScript". Neither of those remedies helped. Any ideas here? Win 8.1, TiVo Desktop 2.8.3. EDIT: Got it installed by running the installer as Administrator.
