Reader keeps shutting down

Hey Peterc, 

As mentioned, your Adobe Reader is keep shutting down. Does it happen while accessing any PDF file or any feature?

Should I dump the Reader program on my Mac and download again?

Well! that's one of the solution, but before that, we recommend to check certain other troubleshooting steps.

1- Update the product to the latest version: Choose Help > Check for Updates and then follow the steps in the Updater window to download and install the latest updates.

2- Turn Off Protected View-

• In Acrobat, go to Edit > Preferences, and then select Security (Enhanced) from the Categories on the left.
• In the Sandbox Protections panel, select Off for Protected View.

• Click OK, and then restart Acrobat DC.

If none of the step helps, then use cleaner tool to remove application: Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs  and reinstall it.

Let us know how it goes.

Thanks,

Akanchha
