Hmm we have a bug report on this issue but it's only been reported on once to twice in total, and in both occasions either a restart or re-install fixed the problem.

If its a new laptop, do you have any windows updates that are installed and pending a restart? This might cause problems installing, I would suggest firstly checking windows updates (Start > Settings > Updates) and make sure everything there is installed and restart your PC. Then after rebooting try uninstalling and reinstalling now and see if it will start?

Thanks
