Fiddler does not start on Ubuntu 18.04

I'm running on an Ubuntu 18.04 server. using VNC via gdm3 (gnome) display manager.

The first time I tried to run progress-telerik-fiddler.AppImage, it brought up a dialog asking if I wanted to integrate with VNC and install a desktop icon, to which I answered yes.

The window then closed, and each time I try to run progress-telerik-fiddler.AppImage again, nothing at all happens, as follows:

wxr-xr-x 1 root root 113958410 Mar 25 14:15 progress-telerik-fiddler.AppImage

There is no desktop icon, log, or anything.
