You're getting that error because you installed the booklet version of KUAL, which won't work on K4. You should be able to fix it just by running the uninstall.bin file from the KUAL archive.

You may run into another issue about expired certificates. To fix that, you need to get the new version of KUAL and install the DevCerts update from here:
