The only GIMP binary that cam be selected is GIMP 2.8. It is not possible to select the newer GIM 2.10.
It's easy to fix. Q: what the different executable files-names used under Windows for the Gimp ? There are release ID in file name ? Gilles Caulier
After a review conducted, i think that problem is about the release id returned by Gimp executable under Windows when you select the file from Print Assistant dialog. Gilles Caulier
