Ahí tienes que trabajar con Types y Components...

Aquí un ejemplo...

[Types]
Name: "full"; Description: "Completa"
Name: "compact"; Description: "Reducida"
Name: "custom"; Description: "Personalizada"; Flags: iscustom

[Components]
Name: "Programas"; Description: "Programas"; Types: full custom ; Flags: fixed
Name: "Ayuda"; Description: "Documentos y Ayuda"; Types: full
Name: "Firebird"; Description: "Administrador Base de Datos"; Types: full compact
Name: "Firebird\Classic"; Description: "Classic Server"; Flags: exclusive
Name: "Firebird\Superserver"; Description: "Super Server"; Flags: exclusive
Name: "Firebird\Client"; Description: "Cliente"; Flags: exclusive

[Files]
Source: "d:\FirebirdCS.Exe"; DestDir: "{tmp}"; Components:Firebird\Classic; Flags: ignoreversion
Source: "d:\FirebirdSS.Exe"; DestDir: "{tmp}"; Components:Firebird\Superserver; Flags: ignoreversion
Source: "d:\GDS32.DLL"; DestDir: "{tmp}"; Components:Firebird\Client;

InnoSetup tiene un ejemplo que se llama Examples\Components.iss...

Saludos cordiales...
