RARSoft nach:
die "Unpacked SFX modules" brauchst Du um andere Bitmaps einzufügen usw...
Originalzitat WinRAR:
"WinRAR does not provide tools or documentation for modifying resources. It is rather complicated process and if you wish to do so, you must already have a resource editor and you must know how to work with it. But you do not need to edit resources if the standard SFX start dialog is acceptable for you."
Viel Glück damit!
