Adding my solution here as well. =)

So I have now fixed my problem. When you select where you want to install the mod (you should make shore its even on the correct harddrive) dont just click on the Napoleon total war foulder and continue. You see when you select the foulder the mod automaticly adds "Napoleon Total War" in to the path. Here is a exampel: "D:\SteamLibrary\steamapps\common\Napoleon Total War\Napoleon Total War\data\NTW3\Launcher". As you can see the mod is not installed in the actual Napoleon foulder but in the added one of the same name. This means when you try to launch it the mod cant find the actual game.

So in short, make sure to remove any extra text the installer adds to your path.
Vive le empereur! =)

I love the earlier verisons of NTW3 so I really want to be able to play this one.

I have tried everything you have suggested. I have unistalled all other mod and earlier NTW3 versions. I have done a clean reinstall of the game and made sure the mod was installed in the foulder with "Napoleon.exe". Every time I try to launch it I get the NTW3 launcher but when I try to launch it it just says: cant find file ../../../Napoleon.exe. Any ideas what went wrong?
