That was exactly it for me! MSI's Afterburner was causing the launcher to crash - something that I've come to expect if I were using EVGA's PrecisionX, yet did not even think of with Afterburner as it is usually so stable. I closed out Afterburner and lo, the launcher works! Thank you for that!

@Schmitzenbergh If you're referring to the OS, it's 64 bit Windows 10. Just to be sure that the Windows install wasn't borked, I did several sfc /scannow runs and it didn't turn up anything. I used that debug launcher (placed all the files in the launcher directory after moving the originals to another folder called ORIG), and these are outputs that I see: 1) Starting up the launcher 2) Checking cmd arguments 3) Starting the launcher 4) Setting-up mainwindow 5) Components initialized 6) ASYNC: Gamerversion == null -> In UpdateVersionMethod 7) ASYNC: Trying to grab Gameversion 8) ASYNC: Getting INI 9) ASYNC: Getting Gamerversion Done 10) Version known, normally starting Then I get a different pop up window that states Renegade X Launcher has stopped working - A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available. I press the close window option, and that's it. Edit: The odd thing is, that launcher stopped working error that Windows throws out only happens perhaps 1 in 4 or 5 times. The other times it just never does anything that I can see, just never shows anything without any active processes that I can find.

I've got the same no launcher issue on two different computers running Windows 10 Pro build 1703, virus scanning software isn't present on the second one. They are both running Nvidia Pascal GPUs, one with 382.53 and the other with the previous 382.33. I can launch the 32 bit udk.exe, yet the 64 bit crashes after a white box on the screen pops up.
