Having the same issue as Militia Man. Launcher does not start and doesn't open any window or report any error. Application log doesn't contain any helpful information either (see attached). I was able to play the game without issues about a year ago when I was running Windows 10 1809. Now running Windows 10 1903. I tried uninstalling, cleaning up folder, then reinstalling. Launcher installs, but won't run. Tried to run as administrator also, but no difference.
Edit (solution found):
Turns out the Renegade X Launcher causes d3d9.dll to fail with exception code 0xc0000005 when RivaTuner is running. Closing RivaTuner allowed the Renegade X Launcher to run. Updating RTSS from 7.2.2 to 7.2.3 resolved issues.
