I'm getting this message from Komplete Kontrol in Reaper. I've followed all the solutions given here - https://support.native-instruments.com/hc/en-us/articles/210276165-Komplete-Kontrol-Error-Message-Loading-Issue-Could-not-load-Plug-in-Windows - twice. Everything seemed to have scanned correctly, but it still doesn't work. (The "Scan Library" button flashes up a window very briefly.)
Any ideas?
