Google the CC cleaner tool for your 'friend'
[EDIT] I'll just add to that, that it is by no means certain to fix things, because goodness knows what the dodgy version to your 'friend's' system.
Already tried this CC cleaner tool. Does not help in this situation.
This is a screen photo of my Photoshop CC and the three lines marked with red are grayed out on his system.
(The menu text is in Norwegian......) His username is not showing and it says log on instead of log off. Is it normal for these three lines to be grayed out? If not, what could be wrong?
You know, I think you would be better taking this to the Creative Cloud forum. There are Adobe staff members on that forum who specialise in CC installation problems, and I think this is going to be a big one.
My bad. I suppose it is not possible to move it myself?
But cut and paste is OK. I will do that.
