if you are using a windows then I can help you! (I was confused at first). Firstly, put the AricsExpansion folder in C:\Users\*your_username*\AppData\Roaming\Strive\mods. Then after go into the folder *IMPORTANT - READ...*. for the first one (name is appdata roaming), put it before the mods folder (so C:\Users\*your_username*\AppData\Roaming\Strive). As for the second one, take the files and put it in the root directory of the game (which you will see strive.exe and other stuff, and there is a folder with the same name as files)! After that, go into the game and don't forget to put the mod in priority of all others.)
edit: there is no .exe, only some files..?
