I’ve just installed fuse for the first time, started it and tried to create a new app using the icon in my menu bar - this didn’t work. I then tried to create a new app using the command line, but got the follwing error (sorry, Shazam just showed a song from the radio at that moment): ![file](https://s3.us-east-2.amazonaws.com/fuse-legacy-forum-assets/5DmxHTZRjb6d-legacy-files-oL5oSCWbAFegENtx-d7hyb1qc2akX_Nqk3Y-Ea_Jp.png) I uninstalled fuse using AppCleaner, restarted my MacBook and installed fuse again. Creating new apps works now, using both the command line and the GUI, but then I try to `fuse preview` the app or start it using the interface, it doesn’t work. The console logs the following: ![file](https://s3.us-east-2.amazonaws.com/fuse-legacy-forum-assets/yaFBg9FA8dgX-legacy-files-K9JQmIiWYrNyOcvo-p3wyKBYMeeH54QaL6bxWwy2J.png) ---

Well, looking at the requirements obviously helps - I didn’t install Mono. Works now, sorry 🙂 ---
