Adding mods does not require knowledge of coding, but Strive is VERY strict about its file paths.
Basically you have the same problem as this: https://itch.io/post/2005618
If you tried to apply the mod, then the problem is the path. This path should exist if you've done everything correct (replace USER_NAME as relevant). Edit: assumed Windows, if not, then replace the path before "\Strive\" with relevant path for user's app data.
"C:\Users\USER_NAME\AppData\Roaming\Strive\mods\AricsExpansion\info.txt"
