I dont know who or where to contact the people making the installer so I'm posting here.
When selecting what components to install there is a wrong explanation for the 1.4.1C patch.
Official EECH patch 1.4.1c (Install for US version of the game)
Well I have the EU retail and after countless uninstalling and reinstalling I finally checked the box for applying that patch. The game just CTD if you dont apply 1.4.1c before applying the community mods.
I think the explanation should read something like "The is required for the modifications below" or it should be ticked by default.
