>From what I can tell, you need to compile the launcher yourself. The source file you need to download from https://sourceforge.net/project/showfiles.php?group_id=200627 is a compressed archive that includes a readme file with detailed instructions. So the first thing you need to do is download this file, extract it, and read the readme. If you run into problems compiling, your distro's support forum would be a better place to ask for help, as that part is not really a Wine issue.
