Activating additionally purchased software options or software maintenance is called "updating licenses".
To update a license with newly purchased software options or software maintenance offline, you need to use the same steps as for activating a license.
Get a new Activation Start file (see Getting the Offline Activation Start File via email).
Create a new Activation Request file (see Creating an Offline Activation Request File).
Get a new Response file (see Getting the Offline Activation Response File).
Process the new Response file (see Processing the Activation Response File).
For updating a license, a new response file must be generated.
Click the Browse link to browse for the request file that has been created.
Upload it to the Hexagon Support Center.
Click Download and save the response file (*.clmresp) to a portable storage device such as a USB stick.
