Same for me. Uninstall/reinstall hasn't helped. I am an administrator but I also tried running as a Standard user on a local account but no joy.
Problems appear to be related to users having UAC disabled. Enabling might fix your issue, but if you always had it disabled you might run into more problems. next version will have an exclusion for the check when UAC is disabled. having UAC disabled basically means any app has admin level access to your system, which is very very bad.
