I have the latest version of Reaper. Upgraded to Kontakt 8.4.1 via current version of Native Access. now Reaper can see Kontakt 8, but it will not load in DAW. it loads fine as stand alone.
this is the error message I get.
The following effect plug-in could not be loaded:
VST3i: Kontakt 8 (Native Instruments) (64 out)
(effects configuration is preserved)
