Hi

I have been attempting to open a few different files attached to emails received or from other file locations, Adobe doesn't open up and eventually had an error message pop up. Failed to connect to a DDE server, Also I have noticed in task manger that Adobe is running a 4 instances of itself.

This has only started to happen since the last 2 patch versions, prior to that it worked ok.

Adobe reader DC Version: 2015.009.20044

AV: System Center Endpoint Protection

Client OS: Win 7 and Win 10 Patch to current patch level

Mail Client: Outlook 2013 Patch to current patch level

Thanks

Leigh

Hi bluecards688248,

Sorry for the delay in response.

Are you are still experiencing the issue?

If you still get the error message "Acrobat failed to connect to a DDE server ", please try the following troubleshooting steps:

This issue generally occurs when you have more than one process of application running

1. Go to the task manager by pressing Ctrl+Alt+Del

2. Go to the processes in Task Manager

3. End all processes related to Acrobat

4. Launch Acrobat again.

If that does not help, try repairing the application. Open the application and got to Help menu > Repair installation.

Let us know if you need any help.

Regards,

Meenakshi
