Some of you might have seen my thread about switching over to 64-bit. So far, everything is amazing. One issue, though: Sibelius 7 won't show up as a rewire device. When I go to insert a rewire device, it's grayed out. I'm running the 64-bit version of X1 AND Sibelius 7 supports 64-bit rewire. So, what's going on?

Hi
Have you updated to X1 D if not do this and that should fix your Re-wire problem

Yes, I did. I'm running Sonar X1 Producer Expanded (which requires the X1D update, I believe).

I read somewhere that, in order for 64-bit Rewire to work, you have to install Sonar BEFORE Sibelius, which I did not do. I did uninstall Sibelius and reinstall it and that didn't fix it. If I reinstall X1, will that fix the problem?

Not sure about Sibelius but I had the same problem with reason
The update to X1 d fixed it for me.

another simple thing is you can't mix 32  / 64 bit.. both have to be one or the other.

does sib. install 32 bit by default or something ? reason I ask is reason will install 64 bit as default and you have to tell it to use 32 bit.

You know, I was wondering about that, Fog. Sibelius doesn't give an option, but I'll check into that.

the other thing you need to watch out for is the x1d update.  there is a separate one for expanded.  if you have x1 installed, apply the x1d patch then upgrade to prod expanded you need to apply the x1d pe patch as well. 

really? Where's that?

Actually, nevermind - yeah, I have the X1d update for Producer Expanded.
