In order to use ArcGIS offline it is necessary to add a license locally to the computer. With the new version of ArcGIS license administrator on the license-server, you may now “borrow” a license for the days you need it (maximum 365 days). Please note that the license is annual and renewed in january.
The video-tutorial is a step-by-step guide on how to borrow a license. It is not necessary to have administrator rights on the computer. ArcGIS must be installed on the computer first. If you don’t have ArcGIS installed, please look it up in “Application Catalog”.
