Cannot open pdf files from shared computer

[Peter22888277z24t]

Running Acrobat Pro 2023 on Windows 10/11.  We recently moved shared files from MS OneDrive to a local computer with a drive shared out to all users on the local network (3 users). 

- Double clicking a pdf in Windows File Explorer on the shared drive will start Acrobat and open the file. 

- But if Acrobat is already open, with or without a file open, double clicking will not open the file.  There are no errors, no stalling or locking up.  It's just ignored. 

- It will open multiple files from the shared drive using File Open in Acrobat. 

- It will open multiple files with a double click from any source other than the shared drive - email attachment, local hard drive, etc.

- All users / all workstations have the same experience. 

It doesn't seem to be a security issue or a connection issue.  

Any ideas?

Hi there

Hope you are doing well and sorry to keep you waiting.

If you are still experiencing the issue, we would need some more information:

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/3wNBiw2 and see if that works.

Let us know how it goes.

Hi Amal,

Confirmed that I am on version 2023.008.20555.  No updates are available.

I performed the repair.  No change. 

I reset the Preferences as specified in the article under Manual Reset.  No change, but Acrobat did not create a new Preferences folder when restarted.  

Any further suggestions?

Further update:  

Turning off Enable Protected Mode at Startup on the Security (Enhanced) preferences solved the problem.
