Going to RGL settings see there installed games choose GTAIV and turning off automatic updates! To avoid RGL updates, you can turn off your internet connection and go offline.

If you can't do it so for RGL version better don't install any textures mods or cars because this increase chance for updates, anyway if you see an update in this way you need to change all files again.

Before installation, if you have in your GTA4 directory the ShaderOverDax1 folder, you should delete it !

After installation, if you want to change the settings again so before you should delete the ShaderOverDax1 folder too !
