No fix I’ve tried online seems to help. Even a fresh install…
Ableton can detect Massive and Supercharger as legit.
Do they also show as ddemo if you open the plug-ins in standalone? I mean outside of Ableton. Is it showing as demo in Native Access too? Then that could be that issue: My products are showing as demo in Native Access
If it's only in Ableton, then try this out: My Updated NI Product Opens as a Demo in My DAW (Windows)
