There doesn't appear to be a native x64 cl.exe with the Express edition, so the only option is to use the 32-bit cross compiler to produce x64 builds.

I'm not sure what the full implications of this are. Ted should be able to review this.

This isn't right. You're modifying the path that's supposed to setup VC11 pro, not express. From your log output it looks like we're detecting your Express install as Pro. :-/

Maybe the logic in guess-msvc.bat needs an update instead?

I have VC 2012 Pro installed here now, so if you want to compare notes on what registry keys are present we can do that.

Bug 903945 has active work on it so I'm resolving this as a duplicate.
