Fatal error - Acrobat failed to send DDE command

Hi all.

We have a third party bit of software which generates reports in PDF format and automatically opens the generated report in Adobe Acrobat Reader DC via SQL. For some reason around 2 weeks ago, instead of opening reports in Adobe Acrobat, it now generates an Adobe Acrobat fatal error, "Acrobat failed to send a DDE command".

We have tried completely removing Adobe Acrobat using the removal / cleanup tool but we're still getting the same problem.  I have followed advise from I have been getting the "acrobat fail to send a DDE command" , and problem still persists.  The only thing I did not do was change was the Log On properties of the Remote Procedure Call service.  I would like to avoid making a major change such as this, but if there is good evidence this is the fix I will revisit this as an option.

This is running on Server 2012 with terminal services.  The current version we are running is Version 2018.009.20050.

Any assistance would be appreciated.

Many thanks,

Greg

Hello Greg,

Sorry for the delay in response to your query and apologize for the inconvenience caused. As per the description above, you are getting an error message of Adobe Reader failed to connect to DDE Server, Is that correct?

Please try the following troubleshooting steps mentioned below:

   1) Make sure that the application is not open to the Task Manager.

  •     Go to the Task Manager by pressing Ctrl+Alt+Del.
  •     Go to the processes in Task Manager.
  •     End all processes related to Acrobat.
  •     Restart the computer.
  •     Launch Acrobat again.

2) Repair the application. Open Acrobat and navigate to Help menu > Repair installation.

3) Check the file association on your system.

Let us know how it goes.

Regards,

Anand Sri.

Hi Anand,

This is an error coming up on a terminal server with multiple users logged in.  However we have tested by closing the acrobat processes and rebooting, but as you may appreciate this is not something we can do often.

I have also repaired the installation, as well as completely removing and reinstalling.

I have checked and reset the file associations on the system as well.

Are there any further checks and tests that we can perform?

Thanks,

Greg

Hi Anand,

I've tried with protected mode on and off (Was already disabled) and still getting the same issue.  I have also added the file locations into the Windows trusted sites and added as a host on the privileged locations settings.  But the issue is still persisting.

I've run the log collector, but the ZIP file generated is empty?

Thanks,

Greg

Hi Anand,

I would contact support for my issue but it doesn't look like there is anywhere I can get support but from the community forums due to it being an issue with Adobe Reader DC. Please advise.

Thanks

Hi Anand,

Adobe Reader DC Version: 2018.011.20038

Windows 7 Enterprise

Office Machine

This all started when we originally had issues viewing certain PDF's in Internet Explorer. Some PDF's would, fairly frequently, render a blank grey screen in the Internet Explorer window or prompt to say "Adobe can't open in protected mode due to compatibility issues" if opening a local PDF that is affected. As a fix to this issue, we disabled 'Start Adobe Reader in Protected Mode' and I believe that is when the DDE server error began happening.

In regards to the "Adobe Cannot Connect to DDE Server" error, I have tried every fix I can find on the forums, including but not limited to:

- Uninstall Adobe Reader with Adobe Cleaning Tool/Reinstall/Update

- Whitelist the server address of the host within Adobe Reader DC.

- Editing registry to disable Adobe welcome screen.

- Verified a different registry key was set to correct value. (AcroViewR18)

- Rebuilt user profile.

- Turned off open in protected mode (This may be causing the issue).

All affected machines are running Windows 7 Enterprise x86/x64 and it's been affecting at least 100 users. Any help or suggestion would be greatly appreciated at this point.

Thanks,

Eniac

Hi Anand,

Any update on this? We have been dealing with this issue for a while and need to resolve it one way or another. We have licenses for Acrobat Pro as well but this issue is only regarding Reader DC. Is there an option to pay for advanced support or what is the next step?

Thanks,

Eniac

Did you ever get a solution? I have exactly and I followed all of your posts and the suggestions from Adobe and nothing works.

I don't know what to do - I'm only marginally techy and this is preventing me from doing my work.

Hello Marye_Ann, 

 

I just encountered this issue, and mine was fixed by disabling the adobe acrobat add in on all office products, and seems to resolve the issue. 

 

Thank you,
