Hello,
Usually I can open an Acrobat file in Acrobat Reader from Explorer at a time. As I try to open to open another file in the same program, it didn’t make any sense.
It didn’t respond at all. After a little bit I am shown the following error message.
“Fatal error: Acrobat failed to connect to DDE server”
Give me a solution please.
Thank you.

Hi Jerry,
Small work around for this problem is to always open your files not using drag and drop method, but by going to the File menu and selecting Open.
There are also few more things to try:
First is to disable protected mode at startup. To do that you should open the Preferences in your Adobe Acrobat, press CTRL+K and under General tab un-check that option.
Sometimes the problem is not in the Acrobat Reader but in some other extensions installed in your browser. Check by disabling them all and enabling them one at the time if one of them has a conflict with your Acrobat Reader.

You might need to check the Acrobat registry entries. To do this, do the following:
1. Open the Windows registry editor.
A. Click Start.
B. Type "regedit" then press Enter.
2. Navigate the following through the tree list view from the left pane:
ComputerHKEY_CLASSES_ROOTacrobatshellopenddeexecapplication
3. Right-click the value from right side of the window and click Modify.
4. Change the value of the key from "AcroviewA10" to "AcroviewR10".
5. Click OK. Close the registry editor.
Check if the issue is already solved.
