installation not working 1.7.0.413

I'm on Windows 8 - I open CC and it prompts me to install 1.7.0.413 - I run the installer and it gets to 100% then it closes the CC window and that's it.

I open CC again and I'm hit with the same update message - have tried it 3 times - closed everything, restarted windows etc, I can't access my fonts and it's damn annoying!!!
