I'm fighting with my old problem: in Vista 64 I only can install the GS4 64bit-Version. And I do want this. But in Sonar8 and Cubase 4 I don't have it for rewirering then. Rewire in Sonar is greyed out and in cubase I only have reason for rewirering. Testing in a 32bit-environment was full successfully. Is it possible to use this feature in Vista 64 generally and if so, how?
