In many "Extreme RIPs," audio is converted to a dummy format to save space. If you don't hear music, check if there is a decode.bat or audio_setup.bat in the game folder. You must run this to "rehydrate" the audio files.

Before you touch the archive, ensure your system is ready to handle the decompression process.

Installing a highly compressed "RIP" version of (often found in .7z or .rar formats) is a popular way to save on bandwidth and storage. However, because these files use extreme compression to shrink the game from 15GB+ down to a few gigabytes, the installation process is more involved than a standard "point and click" installer.

Most RIPs are pre-patched to version 1.0.7.0 or 1.0.8.0 . If yours is version 1.0.0.0, search for the "GTA IV 1.0.7.0 Update" to fix major performance bugs.
