Anand,
thank you very much it works now.
So to sumarize:
I setup ABAP_Trial_7_02_SP11_Win_64_bit_Version_3_387_GB but also requiere ABAP_Trial_7_02_Win_64_bit_1_84_GB because it contains the GUI directory I need for setup.
The secret of port 21212 will still be a secret 
My first impression - there're really less transaction given.
Is there any way to include other modules as eg. SD in the trial?
Thank you very much!
Andre
