Konrad, didn't you have trouble last time with EZD2 not working? Was that you? (You changed your avatar?)
I installed through CCC on my Win8 pc (not my music PC) this morning and everything is working as expected. Went very smooth. I didn't install anything else other than X4 because I already had X3e Dim Pro, Rapture, and all other instruments installed already. I fired up a project that I had with Dim Pro, Rapture, Louge Liz, Session D3, and all worked as expected.
