FMXInno - Windows Fluent Design Installer UI for Inno

[Fak Eid]

You should rather put your "Crack" folder in source than in application installation location. I prefer that.

[Files]
Source: "{src}\Crack\*"; DestDir: "{app}"; Check: ApplyCrack

function ApplyCrack: Boolean;
begin
  Result := Checkbox[1].IsChecked;
end;
