Problems with download

Hi there,
I just wanted to download the noise gate for audacity but I can only open the download link with the editor into a text file.
I have windows 8 with system 64 bits.
What can I do, I am a technical beginner
Thanks for a reply, Chris

Nyquist plug-ins are plain text files, but with a file extension “.ny” (rather than “.txt”).

See here for how to install Nyquist plug-ins on Windows: https://manual.audacityteam.org/man/installing_effect_generator_and_analyzer_plug_ins_on_windows.html#nyquist_install
