No Tools > Nyquist Plug-in Installer?

I am running version 2.4.1 on current windows 10.

To install a nyquist plugin, I am supposed to use Tools > Nyquist Plug-in Installer, but this option is not available under tools.
Under add/remove plugins the nyquist installer is enabled, but just does not show up in tools.
What am I supposed to do?
Thank you for helping me.

There’s now Audacity 2.4.2 https://www.audacityteam.org/download/windows/
Updating to 2.4.2 is highly recommended as it has some important bug fixes.

If you enable the option “Reset Preferences” during the installation of Audacity 2.4.2, I think it may fix the problem for you. If it doesn’t, let us know and we can try something else.
