Every time I start Nuendo, the plugin activation window pops up

Every time I start Nuendo, the plugin activation window pops up.
Even though I deleted all the softtubes in the plug-in path, the activation window still appears.
How can I make it not open?

All installed formats? VST 2 32/64, VST 3?

yes i deleted all of them

Hi,

I sometimes have had issues with Softube’s licencing app. Contact them to resolve this issue. It has nothing to do with Steinberg.

Don’t know about windows but on Mac it can be stored in two different locations
One in the Library in the home folder and the other in the System
you need to check both places.
also not just VST but also AU if you are on Mac
