.dll files
Open file explorer on pc, close all other programs.
Click on "c" drive ( usually your main hard drive ) and open it
Top right hand search bar enter Kontakt.dll and search.
A lot of files should appear in the result ( may take a few minutes ) there will be 64 bit and 32 bit files.
Sort the files in date order, there are buttons at top of screen to do this, sort in latest first.
Then delete all files so you are left with 2 latest dated files, one for 64bit and one for 32bit.
(Note the file dates will not be the date you installed Kontakt, but the computer wiz kid mod dates.)
Remember the path that these file are in, it is best to have them in Kontakt5 folder.
Restart PC
Enter file explorer again and check only the 2 files are where they supposed to be.
Enter stand alone Kontakt and run a few vsts , all should be working ok.
Close Kontakt and then open your DAW.
Open your plugin options or whatever its called in your daw, and make sure the 2 Kontakt dll,s are present as options for Kontakt, and that your program is pointing to these dll files. If you have other plugins in your daw you should see these also if you have a view all plugin choice in your daw.
Open Kontakt in your DAW, and hopefully it will be accepted, then from the plug in choice open up Kontakt in the daw, select a vst and it will open.
Use a user created vst ( a Kontakt modified vst by you ) and it will open.
all ends well, this solved all the error messages for me.
If you have some sound distortion, I had a lot in 5.7.3 then use the Kontakt editor and turn the amp volume button down, then if the output sound is too low increase it from your mixer or speakers. You can tweak the triangular slider ( top right of program ) a little also .
Now no distortion heh ee yippee
