Acrobat doesn't open and is creating lots of subprocesses

Hello everyone,

We have been experiencing issues with Adobe for some time now. Our users are working on an RDS server, and after a while they are no longer able to open PDF files with Adobe. When checking the Task Manager, we can see that each user has many Adobe processes running, sometimes up to 30 processes per user.

The only way to get PDF files working again is either to manually close the Adobe processes from Task Manager or ask the user to log off and reconnect their session.

We are currently running Adobe Acrobat 64-bit version 26.001.21529.
