Could not launch the Registration program. Reinstalling the software may correct this problem

[bradc29946351]

Using Acrobat DC 2021 on iMac on Big Sur, everytime I open it I get the following error (note, reinstalling produces same error):

"Could not launch the Registration program. Reinstalling the software may correct this problem."

Plugin or firewall issue?

Hi Brad,

Hope you are doing well.

Such error message may appear when installation of the application got corrupted. As the error message says, uninstalling and reinstalling the application would work.

Use this cleaner tool for the removal of existing application and its files traces: https://labs.adobe.com/downloads/acrobatcleaner.html?22 

Reinstall it through this link: https://helpx.adobe.com/acrobat/kb/acrobat-dc-downloads.html 

Once done, let us know if that helps. 

Thanks,

Akanchha

Followed the above steps and still had the error. After further research, it was an incompatible plugin. Once that was removed, the registration error went away.

Thank you!
