Issue with Adobe Reader and double double click to open files

[kirop]

Hello guys,

I have a really strange issue with Adobe Reader ( version Adobe Reader 25.001.20435-x64 - automatically updated when a new version is released). So what is the issue:

- windows version - 10 or 11 ( Windows 10 22H2 and Windows 11 24H2) 

- windows server 2022 Datacenter - used as file server

On clients with Adobe Reader, users have absolutely random issue by opening pdf files from mapped drives. I've tested it multiple times by different users, differents OS, different folders, different subfolders, different sizes. Sometimes in the same folder we have some files which are opened by double click and some by double double click. It is totally random. There is no error message, no mouse clock or something. You double click and nothing happens.

No events were logged at that time. 

File assignment is set to reader (I've double checked). 

And here comes the strange thing - If I use Adobe Acrobat Standard 2017 version 17.011.30180.12503 there isn't issue at all. Same files which couldn't be open by double click are now open without any problems.

This can't be a permission issue cause this happens as well in a same folder. 

Does someone have an idea where this issue comes and how to fix it? From my point of view, this is really weird case.

Thanks in advance

Hi @kirop,

Hope you are doing well. Sorry for the trouble with opening files in Acrobat.

Basis the description, here are some suggestions I would recommend you follow:

1. Disable Protected Mode (to test) - 

• Open Acrobat Reader

• Go to Edit > Preferences > Security (Enhanced)

• Uncheck:

  • Enable Protected Mode at startup

  • Enable Enhanced Security

• Click OK and restart Reader.

2. Try UNC path -

UNC paths (\\server\share) are more reliably handled than mapped drives (like Z:\folder\file.pdf), especially in protected mode.

Try creating a shortcut directly to: \\yourserver\sharename\folder and try opening the files from there.

Info around opening files in Acrobat can be found here: https://adobe.ly/4lt4u08

Let us know if this helps.

Hi S.S 

I've tested again and the following happens:

at first I had the same behavior - same folder - some files open without problem some with double double click and as well the option with UNC will not work for us. Too much drama and problems by users.

Then I switch from Reader to Edge - tested with multiple files and no problems at all and pretty fast

Then I swicht back to Reader and change the security settings as you suggested. Here are the original settings:

The protected view was off but I really don't like the idea of reducing security for PDF files. 

Is there something else which could help? Thanks

Hi @kirop,

Thanks for the detailed response.

Another step to try here would be: Disabling the preview pane in Windows Explorer.

Can you check on this and let us know how it goes?

Hi S.S

the preview pane was always off by testing.

Any other ideas? I already informed users to use Edge if they face such problem.
