Looks like it installs but doesn´t work.

Hi. 

I`m having some trouble installing Lightroom CC on Mac. I´m installing it from the CC-app. 

When i press install it sais waiting... and then goes from 1% to 99% in one second. 

In CC it looks like the app has been installed but pressing to open the app nothing happens. 

There is no app dowloaded to my drive either. 

I´ve tried logging out and in of my account - and have done the "repair" of my CC-app, and tried installing Lightroom CC multiple times, but the issue persists.

All other apps in my CC install and work as they should. 

I`m on Lightroom 5.5. 

Any suggestions?
