When you subscribe to mods in the Paradox Mods site, and then run the game from Galaxy, our launcher ought to download the mod files and place them in that /mod/ folder; which it will also create if not there.

If you are manually installing mods, for some reason, then yes you'd also have to manually make that folder.

That /mod/ folder looks right, in general, but as we don't support modded games here I can't say whether you've installed them correctly.

I'm not sure what you mean there, I am sorry.

I suggest you post in the User Mods forum here, as they'll have more experience with manually-installed mods.

Good luck!
