This is meant to be a fix for people either having trouble launching the GOG version of Fallout 3 in Windows 10 and/or people having trouble getting ENB's to work with the GOG version of Fallout 3 in Windows 10.

These steps are only for the GOG version of Fallout 3 because it comes with Game For Windows Live already disabled and with the Large Address Aware fix incorporated that allows the game to use more than 4 GB of your system memory. I don't use the Steam version and can't offer support for it.

I would also recommend, though I don't think it's necessary, to make sure you have the latest Fallout 3 script extender installed. http://fose.silverlock.org/

1. - Make a clean install of Fallout 3
2. - (OPTIONAL) install the ENB of your choice following the authors instructions.
3. - Go to your "Windows/System 32" folder and COPY (do not cut or you may cause issues) a file called
"DXGI.DLL"
4. - Now go to the game folder for Fallout 3 wherever you installed GOG and/or the game. This is the
main Fallout 3 folder, not the data folder
5. - Paste "DXGI.DLL" to this folder and overwrite if prompted
6. - The game should launch normally

You may have to do this again in the future if the game stops running properly. I've had to update it twice myself, but this fix should continue to work for now. I hope this helped you guys continue to enjoy these great games.
