Sudden problems with Adobe on Mac

I have a Mac I-.  Used for years with Adobe to read and print PDF files.

Yesterday, all of the sudden many questions.  Could not print some documents.  Other documents looked very strange, with black background and green type.

Today, the message is that Adobe Reader cannot be opened.  As a result, cannot view or print PDF files.

What is the problem?


Hi jattogox96140952,

Please provide the exact point of the software & OS installed on your system. Also check if it is there any update available for the software after crossing "" help > check updates "»

Follow this thread to reset the Acrobat preferences:- How to reset preference settings in format Acrobat.

Would like to know is what is happening with some or all of the documents.

For printing issues, please refer to this article:- print troubleshoot PDF in Adobe Acrobat and Reader

If the problem persists, then would you please check with the account of another user with Admin rights to reproduce the problem.

Kind regards
