On my Linux Mint 17.3:<p>1. Downloaded the app, opened Nemo and double clicked on the app. Another Nemo window popped-up and the app didn&#x27;t start. Opened terminal and checked permission to find that it wasn&#x27;t executable. The point of the ease-of-use is kind of lost as user would be puzzled and give up.<p>2. How do I uninstall the app? Is it as simple as deleting the file? What if doing that leaves orphan files (that I don&#x27;t know about) that double-clicking on the appimage file could have created? The website doesn&#x27;t mention how to uninstall files?<p>PS: regarding #2 above, I found that right clicking on the Mint Menu entry for the app shows Uninstall option. Clicking on Uninstall removes the entry from Mint Menu. The .appimage file needs to be deleted manually separately (which kinda makes sense). I just hope it hasn&#x27;t left orphan files.
