REVISED (updated on 12th April 2014)
So, we've heard many errors on gta 4. This is one of them.

How To Solve GTA IV SecuLauncher: failed to start application [2000] ?
(Ist try)

1. Go to you games directory.(C:\Program Files (x86)\Rockstar Games\Grand Theft Auto IV)

2. Find LaunchGTAIV.exe

3. Right click the file and select Run As Administrator.
4. Solved.
But this help is not perfect. Many users are not satisfied with this. Sorry to them. So, there's a new trick. That is trusted more than this.

(IInd try)
If still the problem comes.... Then use Razor 1911.
Download the crack Ist of all, then extract it, then copy the extracted files, then paste them in the GTA 4 directory (replace whatever needed). One more benefit of using this crack is that you would have to no more open Social Club!
NOTE:- Please install all the Microsoft Visual C++ and the given DierctX... This was missing... 
If doesn't work for you leave you comment your error will be solved.
