I recently changed my Windows PC and am trying to get my JUCE plugins going again. I had been making legacy VST plugins and testing them in Audacity and Ableton. The “installation” procedure was easy: copy the .dll file to a given folder.
With my new environment, including the latest version of JUCE, I am making VST3 and AAX plugins. I no longer have the legacy VST tools. I have tried the same installation process and neither Audacity nor Ableton recognizes my plugins.
Problem solved! I copied the wrong file. I dug down through a few more folders and found the .vst3 file. Both Audacity and Ableton were happy with it. I will rebuild the rest of my plugins as VST3.
I think I’ve got it now. I move the .vst folder (not just the file) produced by JUCE to my VST folder (\program files\common files\VST) and both Audacity and Ableton recognize the plugin.
