Step 3: Locate Microsoft Visual C++ 2005 Redistributable, more importantly, one's that say something with x64 on end. Apparently this game runs on 32-bit? Im not completely sure, but 32-bit installer comes in the downloaded package once GTAIV is installed.
Step 5: Navigate to the GTAIV main folder, and locate the installers folder. (In my case its Program files > Steam > Steamapps >Common > Grand theft auto iv > installers. People using a disk it would be to right click on your DVD/CD drive in My computer, click explore, and find the folder named "Redistributable"

Step 10: If you're receiving a new error titled "GTAIV FATAL ERROR: RMN40", continue these steps, if not, play the game (Hopefully this worked for you, I could NOT find a solution until I tryed this reccomended by "theunknownsd" on gtaforums.com. He was the one who I found the above solution from, but I figured I would re-do these steps and post them as many places as I could to help other people in the same place I was.
Step 11: If you did get the "GTAIV FATAL ERROR: RMN40" after doing the above, right click on LaunchGTAIV.exe in the main GTAIV folder, and GTAIV.exe in the main GTAIV folder, and make sure that under the Compatibility tab that "run this program in compatibility mode for:" is not checked on all of the launchers. At this point, I got a NEW error once I solved that one, so if you had the RMN40 error, and unchecking compatibility mode fixed it, you may have now received the error "GTAIV FATAL ERROR: WS10", if so continue reading.
Step 12: If you got the "GTAIV FATAL ERROR: WS10", check Add/Remove programs to make sure you have "Microsoft Games for Windows Live Redistributable installed, if you do and you still get the error, uninstall the program at this time.
Step 14: WS10 error supposibly has to do with windows live, so you want to uninstall and reinstall if you already had it, or install it from the folders in step 13 if you didnt have it at all. After uninstalling run xliveredist.msi (Or if your just now installing) and complete the setup.
Step 17: Hopefully now, when you launch GTA through social club, it will load up with no errors. In my case, all of the above got me up and going, there needs to be a hardfix patch for all this BS but I took the time to write this up since I was so mad over it.
I changed from win7 64bit to win8.1 64bit and got the SecuLauncher error message from GTAIV: Episodes from liberty city. GTAIV worked just fine. Reinstalling the Visual C++ 2005 Redistributable didnt do anything.
I got IV to run without securom errors by installing all available patches in order, game runs fine with securom without the dll file as well, signs into social club etc, just doesn't work online because of gfwl.
i dont have microsoft visual c++ 2005 redisstributable in my pc.when i tried to install it a message was showing like "The Windows Installer Service could not be accessed.This can occur if the Windows Installer is not correctly installed.Contact your support perssonal for assistance".what will i do to install it and what will i do to play gta4.plzzzzzz tell me plzzzzz.
