Enabling the Voice Trap plug in

Hi there

I am using Audacity 2.4.2 with Windows 10 on an HP laptop.
Downloaded Voice Trap Direct X version
Moved the two files with the extension .dll to my C/Program Files/Audacity/Plugins folder
Two Voice Trap plugins are showing up in the Tools menu in Audacity - I have changed them from New to Enable and clicked OK
They keep reverting to New and they are not showing up in the Effects menu of Audacity

What am I doing wrong?

Thanks
Carol

The Voice Trap [u]compatability page[/u] recommends the VST version for Audacity.

Voice Trap seems similar to [u]Vocal Reduction and Isolation[/u], already built-into Audacity.
