Under Applications, CCleaner still lists Foxit Reader, although I have completely removed it from my computer, and replace it with Adobe Reader.

How do I fix this?

CCleaner has detected a registry key that was not removed when you ran the uninstaller for Foxit Reader.

I think it's this one: HKCU\Software\Foxit Software\Foxit Reader

You could run the Registry Cleaner to see if it finds the issue. Make the backup if you remove the item.

If you really know what you're doing, you could manually edit the registry.

I'm not 100% sure, so be very cautious about how you proceed.

Thanks, Jamin!

Your idea probably would have done it, but I did it another way which managed to work. I reinstalled Foxit, and then removed it via Revo Uninstaller, which in its full mode does a complete check of all orphaned registry entries and such after the product's own uninstallation method is complete. That did the trick!

Thanks again!

Nice work!

Revo Uninstaller is a great tool and I highly recommend it.
