How to remove unregistered plug-ins

I had four plug-ins that failed to register; so, since the items cannot be deleted in the Plug-ins Manager (“Clear All” fails), I deleted them from Audacity’s Plug-ins folder and purged their footprints in Windows’ registry, after which I deleted the file “pluginregistry.cfg” and rebooted my system. The four items still remained in Audacity’s plug-ins list.

So I edited the configuration file, removing the group of commands for the unsupported plug-ins that showed “Valid=0.” After a reboot, two entries are gone (yay!); but two are still listed; but now, in the “pluginregistry.cfg” file, the two appear as “Valid=1.” I edited the file again but the two items return. Some other file must be generating the errant plug-ins list.

Is uninstalling Audacity and removing its residual keys in Windows’ registry then reinstalling the program the only solution, or is there something else I can try?

Which ones?

The two items that refuse to be cleared from the plugins list are EQCUSTOM.NY and Tunefifh4. The latter one is a 64-bit plugin that I forgot is incompatible with a 32-bit program. Selecting all disabled plugins then clicking on “Clear All” fails to remove the two from the list. Attached in an image. Any other way to delete list entries of removed plugins?

What files are in:

C:\Program Files (x86)\Audacity\plug-ins\

A complete reset of Audacity should remove them.
To do that:

  1. Quit Audacity
  2. From *Users__\AppData\Roaming\audacity* (where “” is your user name), delete the 3 files:
  3. Restart Audacity

Thank you Steve. That did the trick.

I wish you the best imaginable!
