Did you find a solution to this? I have exact same problem in Stylus RMX.
No, and I've tried everything I can think of. If I can I'll try to call Spectrasonics this afternoon.
lowdown: I used the default settings for the install and Omnisphere & RMX didn't initially show up in X2, then I moved the .dlls to the cakewalk/content/vst folder (because that's where the Trilian .dll was) and then they showed up as 32 bit.
I don't understand it, I've never installed the 32 bit versions and I've never had this problem in Sonar before. Later.
