I googled a way to fix it. Uninstalled all that windows live shit with windows install clean up. Tried installing a previous version of it, but it won't let me log in because I have to upgrade apparently.
Restartf your pc and close all other programs taht may be interrupting the installation.
uhmmm, try again tomorrow?
i don't really know, that's my advice
windows restore point. save your shit, then restore
