    Four hours after trying to install this my computer is processing a complete backup restore. Downloading the files was fine until the attempt to run the module .. And then it failed. A file was missingbut could be downloaded from Wiki. The problem was the file was much older than the equivalent file in my Vista Home Premium .. So I tried to register that instead. It partially failed. When I decided I had had enough I tried to return to am earlier restore point but on each occasion this failed. I'm trying a full backup restore. My advice. Is your life worth this hassle?
