Medieval 2 Total War does not work (Install)

Hi!
I have a big problem to get installed my M2TW Gold Edition. I mean I can install the Vanilla Version but not the Kingdom Expansion. It simply does not start a setup but I can play Vanilla but actually no EB II :(

Is there any tweak or thing I might have missed?

Thanks in advance.
Maximus

can anyone help me please? :help:
