Just for info: I tried a lot to fix that crap. I have a WIN 7 64bit host and I ran Cubase 6 and Reason 6 both on 32 bit. I had no rewire option. So, on some people the solutions in that thread helped. Not me and I was really depressed because I resinstalled that shit 15 times or something. Later on I found a folder in .../Programms(x86)/Common Files/Propellerhead Software/rewire. That freaky little folder covered itself in a nasty way. In that folder I found "rewire.dll". For all people who maybe have the same problem in the future I have mentioned above: Copy that rewire.dll into your Cubase Folder, then you have rewire.
