Downgrading¶

What version of LCPDFR should I use?

Latest Complete Edition:

LCPDFR 1.1: Legacy Edition
LCPDFR Compatability Patch

1.0.8.0:

LCPDFR 1.1 Legacy Edition

1.0.7.0:

LCPDFR 1.1: Non Legacy

Why Downgrade?¶

In latest Complete Edition, additional scripts/plugins will not work for LCPDFR. You must downgrade to an older version of GTAIV to use additional scripts/plugins.

How To Downgrade?¶

You must own a legal copy of GTAIV:CE. Please make sure you complete this guide with a fresh/clean installation of GTAIV:CE.

Download & Extract IVDowngrader.
Run IVDowngrader as Administrator.
Next: Browse & Select GTAIV/GTAIV.exe.
Next: Ignore Warning.
Next: Select version 1.0.7.0 or 1.0.8.0. (LCPDFR = 1.0.7.0)
Next: Check (Configure this downgrade for GFWL).
Next: Next on Product Key Information.

Optional

Radio steps, you can pick what you prefer, or can skip entirely.

Next: Select the First Radio Downgrade.
Next: Select Old Vladivostok.
Next: Select Mods (Simple Traffic Loader, DSound, ZMenuIV, ZolikaPatch)

The downgrade should start next. You’ll be prompted to install directx, vsredist, and GFWL. Process will take a few minutes afterwards.

Games For Windows Live

Do not “launch” GFWL marketplace after installation. It doesn’t work, though doesn’t break the way GFWL works.

Gamesaves¶

You’ll be asked to convert gamesaves. If you don’t have gamesaves, you may use these, or just skip converting/these steps.

Start the game once and log into your microsoft (xbox) account.
In the Data/Savegames folder of IVDowngrader, copy the save files and put them into your user folder(s) located in %localappdata%\Rockstar Games\GTA IV\savegames\
