For the first time my Adobe Acrobat X Pro does not open "Fatal Error" "Acrobat failed to connect to a DDE server" means? what I do?

Hi edgarm89348224 ,

Please try these steps :-

Solution 1) (This error occurs when you have more than 1 process of Acrobat 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.

Solution 2) Open Acrobat navigate to Help menu & Repair the installation.

Solution 3) Check the file association on your system.

Solution 4) Navigating to HKEY_CLASSES_ROOT\acrobat\shell\open\ddeexec\application and changing the Key "AcroviewA10"  to  "AcroviewR10.

Let me know if it works.
