FIX: Game wont start after click PLAY

If your game show black screen for second and after this just gone, this solution is for you:

After long time of looking for solution...

1. Run game and set your settings in launcher.
2. Rename file "FalloutLauncherSteam.exe" in game directory" to "FalloutLauncherSteam_backup.exe"
3. Rename file "fallout3.exe" to "FalloutLauncherSteam.exe"
4. Run game from steam.

Generally, the problem is the name of the game file. If you change fallout3.exe to anything else, the game will start.
I discovered it by accident. I used anniversary patcher, which made a backup of the "fallout3_backup.exe" file and when I launched the game from it, it started.

You can name the file as you like, but only with FalloutLauncherSteam.exe it can be opened from steam.
