The Zune Software 4.8 will never pass the checking for updates screen unless i hit the spacebar, then it just does some of the files, and then says its complete, then does nothing. I checked where it puts the files and only some language folders are placed without any dlls or executables.
When i rerun the setup Zune claims to be fully up to date which is obvious bs.
Ive tried the microsoft fixit thingy for the zune software which allows me to retry installing it but it always ends the same way.
This started after i had moved the Zune folder to my C drive because the E drive had to be removed and i hadnt thought to uninstall zune first...
EDIT: After manually editing the registry and removeing every last entry with the word zune in it i got the software to install
