Use a v15 launcher or older: {F7114}
- Start update
- While it's showing that progress bar, click on the X to close it before it's completed
- Start the launcher again and update again
- You'll get an error, press continue and notice the progress bar is stuck
- Close that progress bar again
- Start the launcher for the 3rd time and it will be corrupt, the last temp file (which is very incomplete) replaced the real starmade-starter.exe
