I've downloaded the mw3 two times, and when I try to start the game, apears on a box : LaunchIW5M stop to work

I have all the dlcs ( Collection 1, Collection 2, Chaos Pack and Final Assault ), but this error haunts me, two times the same error with different links of download.

 

Please someone help me and and do not judge me because my English isn't very good :?

My OS's Windows 7 Ultimate 32 bits and and in my first download of mw3 I got play the singleplayer smoothly, without any problem

Expand the error message about LaunchIW5M.exe stop working and post here the content of that error message.

p.s.: piece of advice, LaunchIW5M.exe won't work without DBNetwork.Indigo.dll
