How to uninstall and reinstall Corel PHOTO-PAINT 2018

My clone tool no longer works in PHOTO-PAINT 2018. I tried F8 and it didn't help.

I would like to uninstall and reinstall only PHOTO-PAINT 2018. Is that possible? Or do I have to uninstall and reinstall the entire Corel Graphics Suite. CORELDRAW is working fine and I would like to leave it as is.
