Change the Hostname in License File:

First step is to locate Thinkbox_license.lic, see Location of Installed Files for reference.

Right-click the license file, choose Edit or Open With..., and select a text editor you are comfortable with.

In the license file, to the right of SERVER is your hostname and MAC address, see below:

SERVER hostname-1701E 123456ABCDEF

Edit the file to remove the old hostname and add the new one, don’t forget to save!

Note yes, you can change the hostname but do not change the MAC address. The MAC address is tied into the rest of the license file. If you change this, the file will no longer be vaild.
