Cannot update Kontakt 7.
Native Acces Installer does not work for correction .
Install older version NA does not work.
Deleting Kontakt 7 folder does not help.
So solution at NI support.
No contact form to be found.
Not very happy with NI.
You can use the self-help wizard on this page:
If none of the possible solutions help, you will be able to file a ticket at the end.
Have you tried the NI Uninstall RegTool?
(Also, don't just delete folders. If you're on Windows, simply use its Apps & Features feature.)
"Does NI have human support?"
Counterquestion: Can you read?
