Hello Joel,
Thank you for reaching out about PaperPort 14 not starting on your Windows 11 desktop. I completely understand how frustrating it can be when a trusted application suddenly stops working. You’ve already tried several steps like disabling compatibility mode, running the troubleshooter, repairing Windows and reinstalling the software which shows you’ve put in a lot of effort. It’s understandable to feel concerned especially if this issue started after a recent update.
PaperPort 14 is a legacy application originally designed for older versions of Windows and compatibility issues can occur after system updates. Windows 11 includes a built-in Program Compatibility Troubleshooter that can help adjust settings for older apps. You can try running the compatibility troubleshooter from the Compatibility tab in the program’s properties and follow the recommended settings. If that doesn’t work you can manually set the program to run in compatibility mode for an earlier version like Windows 7 and run it as an administrator. If the issue persists performing a clean uninstall using a tool like Revo Uninstaller before reinstalling PaperPort can help. Another option is to check if Kofax offers an updated version as PaperPort 14.7 supports Windows 11.
Have you already tried running the compatibility troubleshooter and reinstalling the program after completely removing leftover files?
I hope this answer is helpful if you have further questions feel free to reply back
Regards,
Marcelo
