Question

Adobe Error 104 in Terminal Servers

We use a program that holds records.  In this program, we click on attachments that are PDFs and they open in a browser window using the Adobe plugin.  Across multiple terminal servers. Every week we are getting trouble tickets from users saying they cannot view documents.  We go in, try to view a document, and we are getting the error 104.   
  
The ONLY way to fix this, is running the "Repair Installation" feature within Adobe Acorbat.  We have tried using IE, Edge, Chrome, Firefox.  No help.  We have tried running the bProtectedMode registry edit, no help again.    
  
This has been a problem for many years, as seen on these forums themselves, across everything from server 2008 and all the way til now on server 2022, and everything between.    
  
Has anyone ever found a permanent working solution?

    Hi @Nick25520764jaat,

     

    Hope you are doing well. Sorry for the trouble, and the delayed response.

     

    If you are still looking for a solution, you might want to check the browser's Add-ons section to see if ActiveX Control is enabled.

    To do so, go to Acrobat-> Menu-> Preferences-> Internet Settings-> in the Manage Add-ons window, disable any "ActiveX Control" add-on.

     

    Once done, restart the system and try again.
