I want to upgrade to Rhino 5, but I am a little confused over the new availability of 64-bit Rhino. I have two computers I use Rhino (& Grasshopper) on: a 64-bit Windows 7 PC and a 32-bit Windows 7 bootcamp PC (2012 Macbook Pro).

1) Does Rhino 5 come as both versions in one box, or do I have to buy each separately?

2) Moreover, will projects in Rhino 5 (& Grasshopper) made in the 32-bit version transfer and work propperly in the 64-bit version, and vice versa??

Thanks!
