This tutorial will show you how you can have multiple instances of GTA IV installed. This is useful if you are in a clan which uses car mods, but also want a copy which contains your own personal mods, you can the have another which is purely vanilla files which contains every file in case you need backups, since you can copy the file from the clean version, and move it to the modified one.
Step 1: Navigate to your "Grand Theft Auto IV" folder
The first thing you need to do is to locate your "Grand Theft Auto IV" folder. For those who don't know where this is, it's most common location is:
C:Program FilesRockstar Games
However this is sometimes different depending on where on where you bought your game, and if it is a digital, or steam copy.
Your screen should now look something like this:
Step 2: Copy your "Grand Theft Auto IV" folder
Now, you need to right click on the "Grand Theft Auto IV folder, and select copy from the menu, As shown in the screenshot below:
Step 3: Paste your folder in the same place as your "Grand Theft Auto IV" folder
Now, you need to right click on the white space below the folder, and select "Paste" as seen in the photo below:
Step 4: Rename the new folder
Once the folder has been successfully copied, you need to rename it to something so that it is obvious which copy is which by right clicking the new folder and selecting "Rename" something such as "Multiplayer" is suitable.
Step 5: Create a shortcut for the new installation (Optional)
So that we can easily load our clean copy of GTA IV when we want to play online, we are going to create a shortcut on the desktop. To do this, open the newly renamed folder. For example mine would be the "Multiplayer folder" and locate the file called "LaunchGTAIV.exe"
Now right click the file and select copy as shown above. Next, navigate back to the desktop. And then right click the desktop and select "Paste Shortcut"
Once this is done, we can rename the shortcut to something else such as "IV Multiplayer"
If you like, you can even change the icon in the properties of the shortcut.
I hope this helped some of you guys,
