In case that post ever gets deleted, I'll copy-paste what it says here:
#Gta iv original files backup update#
Step 5: In your steam library, right-click GTA 4 Complete, Properties, Updates and choose Only update this game when I launch it (it might be possible now to avoid updates if you launch steam in offline mode, and then switch to online after it's already running, but this is untested or you can just follow A_Sweatband's instructions from his/her comment: ). (overwrite everything since you should already have the game installed) Step 4: Move the contents (only the folders, not the files in the root directory!!!) of the GTAIV folder that you can find inside into your GTAIV folder from SteamLibrary. (don't try this via the old method using the console, it doesn't work anymore) After you write it (careful, no spaces), it will download the files inside a folder called depots. The app will ask for your steam guard code sent to your email or mobile authenticator. Note: You can't use the depotdownloader trick for EFLC because they removed your EFLC license from your Steam account when they merged the 4&EFLC into CE, so your only choice would be to use a backup of the old 1130 version if you have it somewhere, either from a retail version or from an old Steam installation. Step 3: Download DepotDownloader, place it on a partition/hard drive where you have a lot of free space, and then use DepotDownloader (from cmd) to download GTA4 version 1.0.8.0 (latest version with the original soundtrack included it's from November 30, 2016):Äepotdownloader -app 12210 -depot 12211 -manifest 4406763129603688303 -username yourusername -password yourpassword Step 1: Make sure you have the game installed, delete the pc folder, and make a backup of the files in the root folder, you'll need the ones from the newest version, otherwise the old version's securom will prevent you from launching the game
The only way to get it the way it should be (with Schweine - Glukoza playing in the first mission) is this:
#Gta iv original files backup Patch#
There are many guides to patch the game but unfortunately, due to the way CE works is that EFLC's songs for each radio station will play in GTA4 too for those radio stations, instead of the vanilla songs (the radio stations are shared).
