I clicked on Renegade X Laucher.exe in the debug folder, It said, Starting up launcher, Checking cmd arguments, Upgrade preformed reset, Starting the launcher, Setting-up mainwindow, Components initialized, ASYNC: Gameversion == null -> In UpdateVersionMethod, ASYNC: Trying to grab gameversion, ASYNC: Getting INI, ASYNC: CATCH on UpdateGameVersion, ASYNC: Version unknown -> ask to install game.
Then it asked to install the game in the normal window, (the one with the background art, not the setup wizard one, also the first time I got it to appear) then the debug window repeated itself until it reached Upgrade preformed reset, then after it finished downloading Renegade X, it asked to install the UE3 redistributable, and it's been repeatedly doing the "Initializing Download" for UE3Redlist, then a debug window said "Unable to download UE3 Redist (corrupt download)," Now there's no more windows popping up so I guess it's done.
I use Kaspersky for antivirus, no idea if that might cause any problems though.
