Some of my instances have disappeared. I thought it was on my end but i have another computer running Windows 10 and there's no issues.
Im running in Windows 11 and my Kontakt is fully running, maybe you have to update your Kontakt to the last version and try to install some instances in correctly directory and try to scan to find them. If not work, post some screenshots and problem related to make easy to solve.
i figured it out. i uninstalled everything and reinstalled Kontakt. I think i had 2 different versions of Kontakt loaded. 5 & 6. Either way it's running great now.
