Installing Dark Souls on Windows 8.1
Install GFWL in compatibility mode for Windows 7, and as administrator.
Install Sign-In Assistant in compatibility mode for Windows 7, and as administrator.
You should now be able to launch the game.
It may also be useful to install some additional fixes.
Install the graphics fix by downloading DSfix and unzipping it to your game directory.
The mouse fix can be downloaded here and just needs to be put in to the game directory too.
This is what I had to do to get it to work;
