Hi there fellow Ninjas. This is my first post.

I would like to share with you my experience with Gimp 2.8.16. I had a post installation requirement of changing the Interface language to Deutsch [de]. I've spent a full business day searching through posts, blogs and ridiculous recommendations of permanently changing the Interface language for all users.

I am using a setup.exe with the following switches /VERYSILENT /SUPPRESSMSGBOXES /NORESTART /SP- /LANG=de /LOG. As you can see I am using a /LANG parameter. However this only changes the setup language and not the actual interface language.

There are various posts recommending creating a batch file which sets the language and then launches Gimp and non of them worked, of course. Even if you like to save and use an .INF file and try add the /LANG parameter there - it will still not work as it will only change the setup language.

What I've discovered is that Gimp writes language Interface changes in a file named gimprc, located in %USERPROFILE%\.gimp-2.8. Gimp only adds the following string in this file

(language "de") in my case.

Active Setup then can be used to apply this file to all users. Please note, the user folder is created after launching Gimp. However, this file is not overwritten and the application starts in the desired language.

Hope this helps someone,

Cheers
