That is not fusée-launcher for windows. TegraRCMSmash is a fusée launcher, but it is seperate from fusée-launcher.Well what I linked was the fusee-launcher for Windows.
Here it is again in case you didn't read the link originally:
https://gbatemp.net/threads/tegrarcmsmash-a-fusee-launcher-for-windows.502334/
It even says "fusee-launcher-for-windows" in the URL address.
