If you encounter an error saying "Invalid Plugin detected. Adobe Acrobat Reader DC will quit" or "Invalid plugin detected.

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.
