Inno Setup RadioButtons abfragen?

[CReber]

Ich bin jetzt soweit gekommen, das ich mittels dem Inno Setup Form Designer, eine eigene Gui erstellt habe (Lediglich eine einzelne Page!)

Aber wie zum Teufel kann ich nur bestimmte Dateien, bei einem bestimmten RadioButton installieren Ich schnall irgendwie die Logik nicht, obwohl das sogar schon Delphi ist
