Just picked up VEP 7, installed it and ran the VEP 7 Server app.  Scanned the plugins and EVERY Native Instruments scan froze and I was forced to skip them, along with some other odd stuff.  142 VST & AUs in total failed the scan.  I'm on a Mac Pro 7,1 with Catalina 10.15.5.  All my Orchestral Tools, Spitfire and Arturia plug-ins passed the scan just fine.  But Kontakt is the critical one and pretty much the main reason I got VEP 7.  All of my Native Instruments stuff is current/up-to-date, so I have no idea what's going on here.  And the scanning process took me over a half hour, so this is getting a bit frustrating if it's not gonna work.  Apparently it works for some people, but not for me :(....   

ETA:

Not sure what the heck the deal is, but after trying several more attempts to reset and re-scan my plug-ins, all the Native Instruments showed up in AU AND VST!!!  Go figure???
