ProMods

I have downloaded ProMods Canada, and installed all four .scs files into Documents\American Truck Simulator\mod.
I am not using TMP. The Mods do not show up in the mod manager. Any help would be greatly appreciated.

Have you extracted the 7z files to SCS files?
Are you sure you have the correct path and haven't accidentally created a mod folder in the Steam path instead?

I have extracted the 7z files to SCS files, and I am sure of the file path

Can you please provide a screenshot of your mod folder and the game.log.txt

That game.log doesn't show any ProMods mod files being loaded.

Try and do a search for "Freightliner_Cascadia_2018_1.11_MF_2010e.zip" it should lead you to your correct mod folder

After looking at the log, I have found it is from not only the wrong PC, it is from 2020. I can not find a newer log file. I am unsure of what to do next.

Ah right, well you need to locate your documents folder and therein the American Truck Simulator folder. It has to be somewhere on your PC
