After double clicking the the AppImage file downloaded from this website and answering yes to installation of desktop launchers, I was asked whether it was ok to install some additional software named PyPar2. I answered yes and provided sudo authentication at which point a terminal opened which eventually displayed Done. I Quit the PyPar2 installation dialog and observed that several PyPar2 files had been left and no launchers were created. Double clicking the .AppImage flle again prompts for PyPar2 installation. Deleting the .AppImage file and the remaining .par2 files and starting with a fresh .The appimage file had no effect. Please, how do I clean up this mess and start anew. If I must, I will not install the desktop launcher, but I would like to run GIMP 2.9.9 in the .AppImage sandbox.
Thanks for any Enlightenment,
The solution was to right click the gimp-2.9.9 … .AppImage file ==> Properties ==> Open With tab which shows pypar2 then click remove and close. Voila! The .AppImage runs, but without asking to install the desktop launcher. Weird. Anyway, hope this helps someone else. Thanks for your attention to this maddening hiccup. Guess I’ll just create my own desktop files and right click menu for the gimp-2.9.9 … .AppImage file.
