– Bug Within Acrobat

This is common in Acrobat, and you can fix it by restarting the application.

– Corrupted Acrobat

If any component of the Acrobat file is corrupted, it will not function as it is supposed to. The main symptom of a corrupt file in computers is the application failing to run or it ceases to work. 

Corruption may occur due to malware attacking the Acrobat file, wrong or incomplete installation, bad sectors on your hard drive, or incorrect system shutdown.

You cannot fix corrupt software with a simple reboot because the entire application or part of it is damaged. This alters the software’s structure. As a result, it refuses to open or perform an operation you subject it to.

– Out-of-Date Acrobat Software

An outdated Acrobat application has bugs that still need to be addressed and won’t be addressed because the vendor does not offer support for that version. Running outdated software is one leading cause of Acrobat failed to send a DDE server error.

A dated Acrobat app can cause incompatibility issues, especially if your computer runs on an updated operating system. Such incompatibilities may make the software run into issues.

– Conflicting Software

The Acrobat app may conflict with other software on your computer. If you started receiving the error message after installing a software or browser plugin, it could be the one affecting your Acrobat reader DC. 

Usually, the software may block Acrobat, causing it to generate an error message.

Also, if you have an active third-party antivirus on your computer, it could be blocking the Acrobat software. So, try turning it off to see if it solves it.
