Nyqist NoiseGate not showing up in effects [SOLVED]

I am using Win 10, Audacity 2.1.2. I downloaded noisegate in order to eliminate some echo on a video. I added the program to the Audacity/plugins folder, then to "Add/Remove Plugins"and enabled it. When I go to effects, it isn’t there. I went back to the “Add/re…” and it is still enabled. Shuut down Audacity and restarted. Still not showing up in effects.
I noticed that that Nyquist was disabled, I enabled it, but when I go back to that folder it is still disabled.
Am I doing something wrong?

What are your settings in “Edit > Preferences > Effects”?

That was the problem. Nyquist wasn’t checked. Thank You.
