Invalid Plugin detected: Adobe Acrobat Reader DC will quit

Plugins or other programs installed on the computer system may cause problems with the functioning of some software such as Adobe Reader. If the system says that invalid plugin is detected by Adobe Reader, the program will not be able to start. Read on to find out how to fix the issue.

How to resolve Adobe Acrobat Reader DC will quit error message?

If you encounter an error saying "Invalid Plugin detected. Adobe Acrobat Reader DC will quit" or "Invalid plugin detected. Adobe Reader DC will quit" or when using the Adobe Acrobat Reader, don’t worry. It appears that one of the DDL files: "ComposerPlayerControl.dll" causes this issue. To stop this error message remove this dll file.

  • Go to C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\plug_ins
  • And then remove "ComposerPlayerControl.dll".
  • You should now be able to open PDF files without issue.

Alternative solution

If this doesn't work then there is an alternative solution. The issue could also be related to the fact that you also have a Babylon translation tool installed.

In computer systems with the Babylon translation tool installed, Adobe Reader 8.1 often quits due to an invalid plugin error. Re-installing Adobe Reader will not fix the problem. The solution is simple, you need to uninstall one of these programs.

If you need to use the Adobe Reader, temporarily uninstall the Babylon software and reinstall it when you will no longer need the Adobe Reader. Or try to find an online alternative for Babylon, such as Deepl or Google Translate.
