Symptom
KONTAKT 6 does not appear in Native Access and only 'Kontakt' (i.e. no version number) is displayed.
Cause
While KONTAKT 5 and KONTAKT 7 are displayed with their version numbers in Native Access, KONTAKT 6 is just called KONTAKT.
The same applies to the name of the application and the plug-in version.
Solution
Proceed with the installation of 'Kontakt' when installing KONTAKT 6.
You will find the software version number to the right of the product name listing in Native Access.
