winetricks d3dx_41 d3dx9_42 quartz. Otherwise the game will crash on start screen. The exact set of libraries you are installing may differ depending on the exact version you are using. I had luck with v3.04 and the set above. In the worst case you may try installing the whole directx9.
winetricks dotnet20; to make the launcher (victoria2.exe) work. Otherwise, you may always start the game manually with v2game.exe passing appropriate mod options from the command line (e.g.
wine v2game.exe -mod=mod/my.mod)
