Adobe DC opens but then closes

Hey PghPaulie,

As per the issue description, it seems that Acrobat it getting crashed/closed after few seconds of launch? What is the OS you are working on? As shared, you have already tried to run repair, uninstall/reinstall and closed firewall.  Try the further steps suggested below-

• Assuming that you have got the latest version of Acrobat DC. To cross check, Open Acrobat>Help>Check for update or refer to DC Release Notes — Release Notes for Acrobat DC Products
• Refer to the help article here: Resolve Acrobat DC intermittent crashes on Windows and try Solution-3
• For testing, change the following settings under Sandbox Protection following  Acrobat>Edit>Preferences>Security(Enhanced)> disable "Enhanced Security"

Note: Changing the above security settings could pose security risks. We suggest you to turn it back On once you are done with testing.

• If nothing works, then create a "Hidden Admin" and launch Acrobat DC in that.

Create a "Hidden Administrator" user account following the steps shared below and launch the application in that.

1-Hold the Windows Key while pressing “R” to bring up the Windows Run dialog box.

2-Type: net user administrator /active:yes

3-Press “Enter“.

Replace “yes” with “no” to disable the admin account on the welcome screen.

Thanks,

Akanchha
