Acrobat Processes hanging in Task Manager

[Virdual]

I have a client who has been experiencing a persistent issue with opening PDFs in other software. This issue happens when choosing the option to "Open in Adobe" within Outlook email PDF attachments and other software that generates reports.

After some use of Adobe throughout the day, attempting to open a PDF from another program with Adobe Acrobat will result in nothing happening. No event viewer logs, no errors from Adobe itself. The only way to fix it is to go into Task Manager and kill any Acrobat.exe sessions running (even when Acrobat is not open). It seems like sessions are hanging causing new PDFs to not open.

User is running Creative Cloud w/ Adobe Acrobat latest version. We've tried uninstalling, reinstalling, repairing, etc. Not sure what else to do next.

Hi there 
 
Hope you are doing well and sorry to keep you waiting 

Is this an issue with a particular PDF file or with all the PDFs? Please try with a different PDF file and check. If the file is stored on a shared network/drive please download it to your computer locally and then try again.
 
What is the version of the Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the recent version 23.08.20555 installed. Go to Help > Check for updates and reboot the computer once.
 
Also try to repair the installation from the help menu (Win Only) and see if that works.
 
Please try to reset the Acrobat preferences as described here https://adobe.ly/49U5YK3 and check

Let us know how it goes.

I am having the same issue on Windows 11 running Adobe Acrobat Pro ver: 2025.001.20435 64bit.

After opening a few PDF's and closing them trying to open more PDFs fails until I go to the task manager and kill all the active Adobe Acrobat processes that are hanging around. This is very annoying

64 bit version on 64 bit system. Version 25.1.20435
