when trying to play GTA IV. Application Failed to Launch. The application you are attempting to launch failed to start. GTA IV may be blocked by Windows Parental Controls/Family Safety..please tell how to solve this problem. and tell me step by step..
I had the same problem and the solution is very simple your anti virus blocked the game just check the vault of pottencial harmfull files and one of them should be from GTA just restore that file and the game will run again with no problems :)
Just be sure that the anti virus won t think that file is harmful again.
Ok so here's the deal I dont know about computers and stuff but I like games specially gta iv I got the same error after playin it for 2 days beleive it or not when I changed the name of the folder in which I installed gta this problem occurred I searched every where but could not find the solution when I changed it back to the old name tha game start working..... I hope this helps you if you have changed anything before this erreo change it back.
