Not working for me either on new laptop 8.1 - fine on 7 ultimate. just having to do it longhand via google sign in. Don't like the new windows 8.1 - its 'all over the place' - my husband will never be able to use it!Others are having the issue too, have you tried running in Compatibility Mode?
I tried to run both web and offline (30mb) installer in SBIE, but neither installed.
PS: Google doesn't like Microsoft. It's a known fact, since Google blocks Youtube playback on WP devices.
