I've downloaded the 4.20 version of Measure Metrics and have installed everything in the content folders, ran both installers, and the plugin still will not show up in the "About Installed Plugins" dropdown. I am beyond confused and at wit's end.
.. installed and shows up fine for me.. I just copied the three zip files in their respective folders..
NOTE: I put the Appdata in Appdata/Roaming/DAZ 3D/...
Thank you so much for your help! Your pictures cleared things up and led to me figuring out I had the DLL and docs in the wrong directory. Plugin has shown up and is registered and working. Thank you so much!
