Quote:....On Windows one might expect that storing Preferences in the registry
Until recently, Gimp put very little in the Windows Registry, uninstall information, then the devs added a load of file type associations for some reason. Remember that Gimp comes from linux where settings are typically kept in text files. All those xxxxxrc files.
How many different versions of Windows Gimp are you running ?
If only two you might consider running a portable Gimp alongside a regular installation, however
If you look in C:\Program Files\GIMP 2\etc\gimp\2.0\gimprc that is where the global setting are held. see https://www.gimp.org/man/gimprc.html You can change the gimprc location using a command line switch.
Ofnuts has already given an answer here: https://stackoverflow.com/questions/7215...evelopment
Command Line switches & Environmental Variables see: https://www.gimp.org/man/gimp.html (I wonder when the devs will change 2.6 to 2.10 ? Maybe just waiting for Gimp 3 )
