Fallout Launcher won't launch game

[Kashi294]

Okay so here is my problem. Initially I had around 130 mods installed and the game was running fine. I began doing some research cause the game was crashing often enough when I played that I grew annoyed. Following some suggestions I cut down the number of mods I had and installed a few mods that were supposed to improve performance and prevent crashes. After I did this the game would not start. Nothing I did worked. It was working fine before I uninstalled the mods I uninstalled. So I tried to troubleshoot it I.e. verifying the integrity and running the game after uninstalling all mods. I tried to run just the base game, but still nothing worked. So following this I deleted everything from my machine. I reinstalled the game 100% with only the base game files and all the DLC as I have the ultimate addition. I tried running the game using the launcher and still nothing worked. I hit PLAY in the launcher and it acts like the game is booting. The launcher vanishes then after a moment of waiting the launcher reappears and so I hit PLAY again. The same issue repeats.

FIXES I HAVE TRIED!:

I have tried running the game in Win 7 or Win xp comparability

I have edited the fallout_default

I have deleted and let steam recreate the ClientRegistry.blob

I have verified the Cache integrity.

I have completely re-installed the game fresh.

Nothing works please help me!

I'm running Win 8.1, i7 Dual Core processer, 64-bit system,

Okay I have spent many hours combing the internet for a solution and I finally found one. If when you launch the game from the launcher or any other launcher I.e NVSE or Fake full-screen please try and enable the launcher to run in administrative mode. For me this fixed the issue I was having. I went into properties > comparability and ticked the box that read run as administrator.
