acx check plugin

Hi, When I downloaded the acx check plugin and tried to open it, the message came up to choose a program to use to open it. I have no idea what program to use. Any ideas? Thank you!

In Audacity 2.4.2. Tools > Nyquist Plug-In Installer.


“ACX Check” is a “Nyquist plug-in”. It needs to be installed in Audacity. See here in the manual for installation instructions:

Thank you all! I finally got it installed!
