Unity editor 5.5.0f3 (64 bit) hangs on splash screen - Windows 10

Hello all,

I’m trying to get Unity 5.5.0f3 working on my Windows 10 64 bit machine, but can’t seem to get past the Unity splash screen.

The process then idles on 0% CPU, with the blue, circular ‘working’ mouse icon when rolled over.

I’ve tried all ‘fixes’ I could find in a day of Googling, reinstalled many times, cleaned registry - nothing works :frowning:

Any hints where I could be looking for a solution? Could it be something with licensing?

Thanks you very much in advance!

I have the same problem and I’ve just formatted the HD.
