Why Premiere Pro is so sloooooow at startup (not always, only from time to time...)

Normally PP starts in a few seconds on my machines. Once in a while it takes muuuuuuch longer though. Can someone explain to me why from time to time Premiere takes such a long time to start? Is there some kind of scheduled process that forces PP to validate plug-ins and fonts and whatever else it's doing at startup every week or month or what is going on??

Ah! and now as I started Photoshop... this:

So this morning PP starts without any problems, but Photoshop is giving me the finger...
Allright, downloading the AAM now, let's see what happens.

Well, again I'm stuck with the Error 86 and not able to update Application Manager.

Time for a chat with Adobe.

After a remote session with Adobe (44min.), the update went through and the above message is gone. So back to work.

FYI it involved a lot of force-quitting processes from the Activity Manager:

Creative Cloud, CoreSync, CCC Process, CCC Library, Adobe Desktop Service, PC Broker...

Then had to trash Adobe Application Manager from Applications, then trash OOBE from /Library/Application Support, and maybe a few more things I'm not 100% sure, the guy controlling my computer was too fast.
Finally, after all the quitting and trashing, he had me download the Application Manager Installer from Adobe and we installed that. And... Bingo!

Still now with Adobe CC you must have an internet connection open at all times, since you never know when something is gonna get stuck, and the only way to unstuck it is to get Adobe support onboard - via internet/remote sessions.
