Did you disable installing the GTK runtime in the installer? If so, that's the problem. You need to install the GTK runtime environment except it is already installed globally on your system which seems not to be the case.
Try re-installing Geany with the GTK runtime option enabled. -- You are receiving this because you are subscribed to this thread. Reply to this email directly or view it on GitHub: https://github.com/geany/geany/issues/2443#issuecomment-589138483
