Unfortunately, Script Hook V hasn't been updated to support the Epic Games version. If you're playing the game through Steam, this can be found in \SteamApps\common\Grand Theft Auto V\. Copy ScriptHookV.dll to the parent GTAV folder.There are two tools you need to download first: Script Hook V and GTAV LUA Plugin.
Unfortunately, installing GTA 5 mods on PC isn't as simple as copy and pasting the downloaded files across.
