acrobat reader server failed

Hi there!

Sorry to hear about the consistent problem with the Acrobat. Are you working with Acrobat DC or any previous version?

Since you have already tried the changing the registry settings as well as checked the update as suggested in the help article here: Fatal error - Acrobat failed to connect to a DDE server

• I would like you to try changing the below preferences setting of Acrobat once and see if that makes a difference.

For Acrobat Reader,Navigate to Reader>Edit>Preferences>Security (Enhanced)>disable "Protected Mode at Startup" and "Enhanced Security">OK>Reboot Reader Security">OK>Reboot Acrobat

Note: Changing the above security settings could pose security risks. We suggest you to turn it back On once you are done with testing.

• Open Acrobat/Reader>Help>Repair Installation
• Still doesn't work, use cleaner tool to remove the application: Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs and reinstall it.

Do share the result.

Thanks,

Akanchha
