My paid adobe acobat not able to Open

Hello,

I hope you're doing well, and we apologize for the delayed response and the trouble.

As our community expert correctly highlighted, you can use the Acrobat Cleaner tool to remove corrupt or conflicting installation files and reinstall Acrobat. Restart your machine and check if the issue is resolved.  

If the problem persists, please collect the crash logs from your device and share them with us for further investigation.

Thanks,

Anand Sri.

@doraz_6843  The error "a running instance of Acrobat has caused an error" usually means that Acrobat (or a related process) is still running in the background, even if you don't see the main window. Your reinstallation should have addressed this, but sometimes remnants linger.  Wait until it is 100% complete.

Then re-install the software

Use Adobe Cleaner Tool to fix the many common problems (such as removing old Adobe software, cleaning corrupt installation files, and fixing your host files to establish a connection with Adobe servers).
