Please ensure that ArcGIS Pro is launched as an administrator in order to register GISquirrel.
ArcGIS
This command opens a form showing the details of your existing registered licence, and allows you to enter new details if required.

Licences can be purchased online or direct from exeGesIS SDM Ltd. After purchase you will be sent a 25-character registration code. This should be entered along with the name you gave us when purchasing (usually an organization name, but can be a personal name). The number of seats licensed is encrypted within the registration code and will appear automatically when the information is correctly entered.
Note that the entire registration code can be pasted into the first box.
Licence registration details should be entered on each licensed PC.
If you want to purchase licences for additional seats, you can do so from www.gisquirrel.com or direct from exeGesIS. Please make sure you give us the same licensee name when you order, and we will supply you with a registration code for the total number of seats held.
When upgrading to GISquirrel from ArcSquirrel, you will need to re-enter your licensing information; otherwise licensing will be carried forward from the previous installation.
