NOTE: None of this applies to custom campaign mods as those will continue to work as they currently do.
Mod packages that simply include modified graphics, sounds as well as possibly localization text, that will overwrite the game defaults, must be formatted to the following folder structure and installed to the USER Mods folder in order for the game to properly locate and read the modified files.
Example:
Users\<username>\Documents\My Games\Strategic Command WWII - War in Europe\Mods\<modfoldername>
Users\<username>\Documents\My Games\Strategic Command WWII - War in Europe\Mods\<modfoldername>\Bitmaps
Users\<username>\Documents\My Games\Strategic Command WWII - War in Europe\Mods\<modfoldername>\Interface
Users\<username>\Documents\My Games\Strategic Command WWII - War in Europe\Mods\<modfoldername>\Sound
Users\<username>\Documents\My Games\Strategic Command WWII - War in Europe\Mods\<modfoldername>\localization.txt
Mod packages that also include modifications to the default campaigns can be installed here as well.
Example:
Users\<username>\Documents\My Games\Strategic Command WWII - War in Europe\Mods\<modfoldername>
Users\<username>\Documents\My Games\Strategic Command WWII - War in Europe\Mods\<modfoldername>\Campaigns
Users\<username>\Documents\My Games\Strategic Command WWII - War in Europe\Mods\<modfoldername>\Campaigns\_1939 Storm over Europe
Users\<username>\Documents\My Games\Strategic Command WWII - War in Europe\Mods\<modfoldername>\Campaigns\_1939 Storm over Europe\Bitmaps
For an example of a proper grahpical mod folder structure that can easily be dropped into the game, please refer to IronX's custom graphical mod for World at War found here:
tm.asp?m=4584600
In game turning on or off a graphical mod will look like this where the mod folder name will be listed in the Mod selection screen:
