# Offline activation of License Files

When protecting a cross-platform app with License Files, in the event a  client does not have an internet connection to activate a license online, you can perform an **offline activation** as described below.

**1. From the QLM Management Console**

* In the QLM application, under the Manage Keys tab, locate and select the license to activate.
* Click on the Activate button.
* Fill in the Computer ID field on the Activation tab along with other fields as required.
* Click on the **Advanced** tab.
* Select a location where you would like to store a license file on your system then click Ok.
* Send the generated license file to your customer and ask them to copy it to the folder where your application expects the license file to be located.
