I wrote it up a few times… heading to bed so here is a quick stream…
Basically I just install the second version in its own directory…
Then create a folder to use for the config files…
Take your current windows shortcut and copy it…then just go into the command line and adjust the paths for that new installation folder…if you just add like _AGX then that is all you will need to do there wrt editing the path name…and then just add --configdir “use the path to a new folder for config files”
So install in a unique dir and then make one more folder some where that you can use for config files and use the command line to point to it…
When ever you update the second version ie the agx one never say yes to uninstall just install over the top. The uninstall would hit your main instance of DT. And be sure that you select the second directory if you update the AGX one because if you just keep hitting yes it will use defaults.
I would turn off sidecars in the agx version to avoid mistakes and keep your test images separate…that should be all you need to do…
I do a bit extra but its not needed…
“C:\Program Files\Kofa_DT2\bin\darktable.exe” --configdir “C:\Kofa2” --tmpdir “C:\Kofa2” --cachedir “C:\Kofa2”
“C:\Program Files\Kofa_DT2\bin”
