When you see the UAC (User Account Control) prompt, click Yes to grant admin access. To do this, navigate to the location where you installed GTA 4, right-click on the game’s executable, and click on Run as administrator from the newly appeared context menu. Several affected users that were previously dealing with this problem have confirmed that they managed to fix this issue by modifying the default behavior of the game’s executable and forcing it to launch with admin access. In case you are encountering the SecuLauncher failed to start application error with GTA IV after you installed it from a traditional media (not via Steam or a different Game launcher), this problem can also occur due to insufficient permissions. Method 1: Running GTA IV with Admin Access DLL file that will bypass SecuROM verification (IPHLPAPI.DLL) Since this is required to pass the SecuROM verification, you need to install the latest GFWL version in order to fix the issue in this came.

Passing SecuROM verifications – Even though the GFWL (Games for Windows Live) component is obsolete by now, you still need the latest version if you are running the game from a traditional media.

If you’re seeing this error on Steam, force the launcher to perform an integrity check and download any missing files that might produce this error.

Corrupted game files – An inconsistency with the installed game files of GTA IV can also be the underlying cause of this issue.

Launcher incompatibility – In case you try to run the traditional version of the game (installed from a DVD) on Windows 10, you might need to enable compatibility mode with Windows 7 or Windows XP before you will be able to run the game in a stable manner.

If this is what’s causing the problem, you should be able to fix the issue by installing the missing package from the official Microsoft download page.

Missing Visual C++ Redist package – Another fairly common cause that might produce this error is a missing Visual C++ 2005 Service pack 1 Redist package.

This permission issue can be resolved swiftly by modifying the executable of the game, forcing it to run with admin access.

Missing Admin Rights – If you launch the game via the standalone launcher (not via Steam) on Windows 10., then you need to ensure that the game is forced to run with admin rights.
