When launching FiveM unofficial multiplayer for GTA 5, you may get an
CitizenFX Fatal Error Could not load dependent module steam_api64.dll Error code was 1114
This is probably because you are using a retail version, while this only works on Steam version, or you don’t have Update 5 files installed, or you are missing some of the FiveM multiplayer files. So get a proper version and a proper update, and copy in all FiveM files. Another
CitizenFX Fatal Error Could not load dependent module 3d9.dll Error code was 119
is similar in nature – you are missing some of the files. Copy over the FiveM once again. All the rest errors when entering FiveM multiplayer or inside it are related to the poor quality of FiveM itself and could only be patched by the FiveM team.
