CLC licenses are specific to a particular machine. In particular, the machine that the license file was downloaded to is the machine that it is tied to.

Static licenses are tied to the machine the Workbench is running on. In the case of network licenses, which are served by the CLC License Server software, the license file(s) are specific to the machine the License Server software is running on.

An error like "The requested license order is not available for the specified Host ID"  means either that

• you are trying to download a license to a different machine than it was downloaded to before,  or that 
   
• the MAC address of the machine has changed since the last time you downloaded the license.

We provide information about the steps required to move a license from one machine to another, or in the case where the MAC address of a machine has changed in a related FAQ:
