Acrobat (unified) Pro on a Windows 2019 RD Server - User profiles not deleted

Hi,

I am adressing an old problem where, when a user logs off from an RD server, his temprorary profile (mounted user profile disk in this case) in C:\Users\ isn't deleted because there are files stuck on the following path:

C:\Users\[USERNAME]\AppData\Local\Temp\71\acrobat_sbx

The files have a Z@XXXXX.tmp name, where the XXXXX are random characters.
The in the path 71 appears to be a random number.

I'm having difficulties in reproducing what exactly goes wrong and creates these files there.

It looks as if it doesn't occur with every PDF (we get a lot, being a printing company) and earlier documentation on this suggests it happens when a PDF is getting printed.

With administrator rights I can delete the orphaned profile folders, perhaps even automate the process, but I'd rather see that this didn't happen at all.

Searching the net results in articles that claim a certain update has solved the matter, only for it to arise again, like a phoenix from the ashes, after a while. I'm a bit stuck here, some help would be appreciated! 🙂

And as it is almost new year, all the best!
