Hey There !
So As someone stated since the start of this thread, this is a problem of permissions.
But for me, launching it as Administrator directly from right-click didn't work ... Which is odd because my solution do basicly the same thing.
I managed to resolve the issue by going inside the installation folder and doing 2 things :
For "iCUE.exe" and "iCUE Launcher.exe" we have to put them as launching as administrator ( well it differs for all windowses ... That how to do on W10 : Right Click > Properties > Compatibility > Modify parameters for all users > Execute this program as Admin )
- Just to make sure it doesn't shift permissions after it have been launched, I also put iCUE.exe Security parameters as of full control to all users. ( Properties > Security > choose Users on top, Modify > Check all autorisations )
That solved it for me :) ! The only downside is the Admin Rights prompt as soon as you launch Windows ;) !
I hope i helped many of you there.
