Reinstall Rhino on new computer

I have Rhino 4 and upgraded to Rhino 5 with an Rhino 5 upgade disc. How do I install Rhino 5 on my new computer - do I have to install Rhino 4 from a disc first, and then Rhino 5 upgrade from the next disc?

Best regards Lene

No, not necessary to install V4. The V5 upgrade version will ask you to enter the V4 license key at the time of installation is all.

Why discs? Please use your registered email and license key to directly download the recent Rhino 5 installer from rhino3d.com. Cheers!
