Just downlaoded the latest portable version again for testing before posting this.
From: https://portableapps.com/apps/graphics_pictures/gimp_portable
I was trying to use Batcher, a python written addon, updated for GIMP 3 already. And installing it won't show up in the portable version but will show up in the installed version. Tried couple times.
I looked up the plug-in browser of each version and screenshoted each but can't upload here, sadly.
When typed "Python" into the search box of said browser, only "Python dictionary" showed up in the portable version.
But in the installed version, I will also get "Plug-in example in Python 3" & "Python Console". Does that matter?
And mostly importantly, how do I "install" it?
And will that be added in later releases?
Within this version GIMP 3.0.4 portable, two files need to be updated, then python will run again:
C:\PortableApps.com\PortableApps\GIMPPortable\App\pygimp.interp
python=PYTHONWDEFAULTPATH
python3=PYTHONWDEFAULTPATH
/usr/bin/python=PYTHONWDEFAULTPATH
:Python:E::py::python:
C:\PortableApps.com\PortableApps\GIMPPortable\App\gimp32\lib\gimp\3.0\interpreters\pygimp.interp

python3=C:\PortableApps.com\PortableApps\GIMPPortable\App\gimp\bin\pythonw.exe
