what do you mean by preconfigured?
IC choosing the .exe file automaticly?
That does not work, in generel game have more than one executable, IC wouldn´t know which is the correct one.
Just go to Executable-tab, click ADD, Fill name and executable-path like {app}\Binaries\win32\win32_shipping.exe (for example), check that desktop and startmenu are activated (blue background).
then add the internal/external media.
And keep an eye on the folder-structure, like inge pointed out. sometimes things get confusing
