I’ve been using GIMP installers from partha.com because it comes with things like G’Mic and Nik already set up. But 2.10.30 is available from the official source. Tried to Google a page that tells me if I can use the official updater, without losing my groovy partha (2.10.22) add-ons?
Given that the plugins in Partha’s have been compiled for 2.10.22, you can likely copy them over in a 2.10.30 installation. In practice if you want to be safe, you copy them to the plug-ins directory in you user profile.
Once you have done that you will even be able to update to a potential 2.10.32 without having to do anything to keep your plugins.
Coincidence, a question about Google-Nik / Windows Gimp 2.10 came up on another forum yesterday. (although I am really a linux user)
First thing to do is go into the Partha system plugins folder and back-up the plugins you need.
Gimp 2.10.30 installs to a different folder to Partha. Both can co-exist until until you decide to uninstall the older Gimp.
Those backed-up plugins can go into your regular Gimp User profile plug-ins folder. (plugins go there, not the system folder)
C:\Users"yourname"\AppData\Roaming\GIMP\2.10\plug-ins. Since you started with Partha Gimp 2.10.22 that will already exist, some settings might screw things up. You might have to rename it and run Gimp 2.10.30 to make a new empty default, then add the plugins.
…and for Gimp 2.10.30 you find in the same place in the Filters menu:
The gmic plugin should be easy, get the Gimp installer, run it, it will find the Gimp profile and install there. Again there is a gmic profile C:\Users"yourname"\AppData\Roaming\gmic Many changes from the old gmic, best delete that and let gmic make a new one.
I’ve only corresponded twice with Partha, and he always seems cheerful. I too hope he is just briefly distracted.
Thanks for going into the details of the “system” folder (“program files” on my 64 bit) and the App Data folder which I only vaguely understand.
Also, you guys reminded me to copy out the paths from the existing Gimp install; easier than digging thru folders to investigate location. Existing Gimp paths will always be right (for that version anyway) .
