If you’ve already installed your software update and you are just updating the license file, you can over-write your existing license file in the Axiom base directory. For a default installation this would normally be:
C:\Program Files\Axiom\V?\ or
C:\Program Files (x86)\Axiom\V?\
(The “?” indicates a version. For example: “C:\Program Files (x86)\Axiom\V8”.)
If you have not installed the software update yet, place the license file anywhere and start your installation. During installation, you will be prompted for the license at which point you can navigate to wherever you saved it.
