So I decide to buy both games from Frys electronics store (retail disk). When I get home to install them and try to play they don't work, I have patched them to the latest patch and nothing. When I try to run GTA IV I get this error: "SecuLauncher: failed to start application [2000]" When I try to run the game as admin I get this error: "GTA IV has stopped working" When I try to run GTA IV in compatibility mode with Windows XP Service pack 2 I get this error: "SecuLauncher: failed to start application [2000]" When I try to play GTA EFLC I get this error: "EFLC has stopped working" When I run EFLC has admin I get this error: "EFLC has stopped working" When I try to run the game in compatibility mode with Windows XP Service pack 2 I get this error: "SecuLauncher: failed to start application. [2001] -> 0x00000002". Please help me fix this problem.
