Plug-in not showing up

[MrsP-from-C]

Quote: C:\Users\jack6\AppData\Roaming\GIMP\3.0\plug-ins AND 
 C:\Users\jack6\AppData\Roaming\GIMP\3.0\plug-ins as plug-in directories.
(Why 2 locations I am not sure, so I put the script directory in both.)

Are they really the same?
Normally you have two: one is yours and one is GIMP's (GIMP's gets overridden on updates)
That's why you have two.

The plug-in does not show?
Have you put the complete unpacked folder into your plug-ins folder?
And ... don't put it in both folders, that won't work.
