[FIX] SecuLauncher: failed to start application [2000] error


Recommended Posts

Alright here is the fix for the Error:


SecuLauncher: failed to start application [2000] error:


Now alot of forums (even this one) says you need to uninstall your 2005 Visual C++ package and any others that came after it, and install the one that came with the disc. However I found this isn't the case.


If you do uninstall it (like I did). You will find you may have a new version of this package installed, blocking you from reinstalling it. So you will have to uninstall the new package (most likely a 2010 redistributable) and then you can install the package off the disc. Or if you downloaded the game from Steam (as I did), from the installers directory.


You may have also heard this came was meant for XP. This is simply not the case. Thats not what the error means.


I am currently running the game on Windows 7 Home 64bit and Windows 7 Professional 64bit. Without issues.


Simple all you need to do is locate the following files:


C:\Program Files (x86)\Steam\SteamApps\common\Grand Theft Auto IV\GTAIV\Activation\SteamActivation.exe

C:\Program Files (x86)\Steam\SteamApps\common\Grand Theft Auto IV\GTAIV\LaunchGTAIV.exe

C:\Program Files (x86)\Steam\SteamApps\common\Grand Theft Auto IV\GTAIV\GTAIV.exe


Right click on each of them, and check the box to allow them be Run As Administrator. The game should run successfully.
