You don't need to make use of the [code] section to add an automatic starting app.

There are different ways to accomplish this, for example

[icons]
Name: "{userstartup}\My Program"; Filename: "{app}\MyProg.exe"; Tasks:StartMenuEntry;
Name: "{commonstartup}\My Program"; Filename: "{app}\MyProg.exe"; Tasks:StartMenuEntry;

The difference between {userstartup} and {commonstartup}, if not obvious, is that {userstartup} affects the startup menu entry for the current user and {commonstartup} affects all the users of the target machine.

Edit

You may also use the registry to start an application. I'm adding this because the OP mentioned in comments the described method doesn't work on windows 8 (because the lack of start menu, which I forgot). I have no windows 8 at hand to test, so it's up to you to test if this works on windows 8 or not.

The Run keys in the registry exists since WinXP, so you can configure windows to auto-run a program from the installer adding something like this:

[Registry]
;current user only
Root: HKCU; Subkey: "Software\Microsoft\Windows\CurrentVersion\Run"; ValueType: string; ValueName: "MyProgram"; ValueData: "{app}\MyProg.exe"; Tasks:AutoRunRegistry;

;any user
Root: HKLM; Subkey: "Software\Microsoft\Windows\CurrentVersion\Run"; ValueType: string; ValueName: "MyProgram"; ValueData: "{app}\MyProg.exe"; Tasks:AutoRunRegistry;

Don't miss I'm also changing the Tasks parameter in the example to AutoRunRegistry.
