Advertisements I got screwed last nite when I had 2.3a running on Vista Home Premium edition and tried to install 2.4a - which had me uninstall 2.3a and then told me that it wouldn't install unless it was under XP-Svc pack 2. So I've been trying a slew of things all nite long but this is what finally worked for me: 1. I disable User Account Control on Vista 2. I disable my anti-virus/security program 3. I uninstalled Tivo Desktop 2.4 4. I search my PC for any Tivo references and deleted everything with the exception of the .tivo recording I had in My Documents 5. I went into the Registry and did and find & delete on every Tivo reference 6. I restarted my computer, just out of precaution. 7. I editted the properties on the TD2.4a install file and set the Compatibility to Windows XP SP2 (Right-click/Properties/Compatibility Tab) for yourself and all users. 8. I followed the "How To Run TivoToGo 2.4 on Windows Vista" directions at "pvrblog" dot come site Good luck. it took me all nite after doing step 1-3 and 7-8 without any luck and getting the annoying message that the Beacon Service wasn't Running.
