Common causes include missing or corrupted Microsoft Visual C++ Redistributable packages, outdated .NET Framework versions, compatibility issues, or damaged game files. Conflicts with antivirus programs, issues with Rockstar’s DRM system, or incorrect system settings may also cause this error. In this article, we will discuss different ways to solve this error.
1. Run GTA IV with Admin Access
Giving administrative access to GTA IV and its SecuLauncher bypasses operating system restrictions, allowing it to access needed system files and permissions for proper startup. To do this, navigate to where you installed GTA 4, right-click on the game’s executable, and click on Run as administrator from the context menu. When you see the UAC (User Account Control) prompt, click Yes to grant admin access. If the game launches without the SecuLauncher failed to start application [2000] error, you have confirmed an admin access issue. Leaving things as they are will require you to repeat this procedure every time you launch the game. However, you can modify the default behavior of the game’s executable to ensure it always opens with admin access. Here’s how to set up this default behavior:
2. Install the Visual C++ Redistributable Package
Installing the Visual C++ Redistributable Package solves the problem by adding important parts GTA IV needs to work correctly. These parts ensure the game can run smoothly, fixing errors from missing or broken Microsoft libraries. Note: You must install the version that is compatible with your OS architecture. To install the Visual C++ 2005 Service Pack 1 Redist Package, follow the instructions below:
3. Run the Game in Compatibility Mode (Windows 10 Only)
Sometimes, older games like GTA IV have trouble running on newer operating systems due to compatibility problems. Running the game in compatibility mode makes the system act like an older version of Windows, which helps the game run correctly. This can resolve issues caused by newer features in Windows 10, allowing the game to launch properly.
4. Verify the Game’s Integrity
Checking the game files can fix the SecuLauncher error by finding and replacing any missing or damaged files. This process ensures the launcher has everything it needs to run the game correctly.
5. Install GFWL
Installing Games for Windows Live (GFWL) can fix the SecuLauncher error because GTA IV needs specific GFWL components to work correctly. Without GFWL, important files and services may be missing, causing launch problems.
6. Bypass SecuROM
Using a workaround to skip SecuROM can fix problems caused by this old DRM system, which often doesn’t work on modern operating systems. By avoiding SecuROM’s checks, the game can start without facing compatibility or authentication issues. This approach ensures the game runs smoothly without DRM-related disruptions. To apply this fix, download the IPHLPAPI.DLL file and use a tool like WinZip, WinRar, or 7zip to extract the contents directly into the game path (in the same directory where you have the GTA IV executable).
