Client won't open/ stuck in update load

I waited a while trying to get my regular launcher to update but it never moved from the first league logo and into the actual client. It didn't even load up a single section of that first bar. I uninstalled to see if reinstalling would fix it but now the installer won't even open.

I had yet to install pbe from getting my new computer so I decided to try that one as well and the installer for that won't open either.

Please help.

EDIT: I did a hard shut down on my computer (Held down the power button which i know isnt good for it but) and it fixed it. My PBE is installing at least.
