The Smarter scripts installation is just packing the scripts and installing that file through MO/Vortex, but you still need to place the dll and exe files from SKSE into the Skyrim folder (where the skyrimse.exe is).
That file path contains the ini, logs and save files. Your game should be under …SteamSteamappscommonSkyrim Special Edition. That’s where you need to place the dll and exe files from SKSE.
