Need Rhinoceros Version 4.0 SR4b download link?


I had bought Rhinoceros Version 4.0 SR4b and now lost our CD. I want to install it in another computer. How do I go about it?

Also, Is it possible to use 1 license key on two computers?

Assuming that you registered your license, contact McNeel directly at

Yes, you can install it on all the computers that are owned by you but you can only run it on one machine at a time.
