Product: Zoo 4.0
Summary: Solving the “This license of Rhino is expired” problem
We are having difficulties getting Rhino 4.0 working in network-node mode on our Windows 7 64-bit workstations. We have one workstation that is working and that had SR8. The others that are not working are SR9.
When starting Rhino 4.0 the client receives a message stating that This license of Rhino is expired, and offers the choice to Upgrade this license, Enter a new key, or Close Rhino.
How do we resolve this issue?
This error message is incorrect: The licenses are not expired. Instead, the problem is that the license file in C:\Program Files\Rhinoceros 4.0\System\Rhino.key is not writable by Rhino.
The fix is easy.
Rhino 5 does not have this problem since it is designed for Win7 and the complications of UAC.
