Hi does the latest Kontakt 6.71 work with Windows 8.1? My kontakt 6 is working but I got a plugin that works only with 6.71
Unfortunately, no. Since version 6.7.0, the minimum supported Windows version is now Windows 10:

(click the spoiler warning thing there)
Native Acces won't let you download the installer, but if you can get the installer from a W10 machine, you can copy it over to your 8.1 machine and it will work.
