SOLVED, SORRY FOR DISTURBANCE
I installed not Pro version by mistake.
Hello,
I've just installed 7th version both on Mac mini M1 and two PC's under Win 10.
Mac version has found plugins, but PC does not.
I have also old 5th version on this PC. I copied all plugins directories from 5th version to 7th. New version scans about a minute, but nothing arises in Preferences/Plugins section.
What can be the reason?
