Hello,
Install the game, including the addon and patches.
Apply the propper cracks and test if everything is working ok.
( I did not adjust any game settings, just left them default).
If everything works to your liking, just create an installer package
of the game dir with InnoSetup. [ hxxp://www.jrsoftware.org/download.php/is.exe?site=1 ]
( I uploaded the script I used for your convenience ).
Please read the script and adjust the paths to your own situation.
I also uploaded the Icon I used for the script.
Good luck
