Most of my mods require version 2372 of GTA V. Here's a quick and easy guide on how to get that version.

Note that this will wipe all your .rpf based mods as well as your savegames!
You'll have to reinstall any .rpf mods after the downgrading process is complete.

Downgrading

• Download the downgrade archive.
• Delete your mods folder, if you have one.
• Extract the contents of the .zip into your game folder, replace all if prompted.
• Run the game.

Additional notes

• ScriptHook is already bundled with the downgrader, you don't need to get it separately.
• If you're using the Rockstar Launcher version, you'll now have to start the game via PlayGTAV.exe in the game folder instead of the launcher, as it auto-updates otherwise.
