Licensing the Software
GWv4 License
GWv4 requires either a software license or a hardware dongle to be installed to edit GEMS calibrations and connect to GEMS ECUs (apart from the demo calibration).
To purchase a license key for GWv4, please contact GEMS.
Once your order has been placed and payment cleared, you will receive an email with your license key from licencing@gems.co.uk.
XCP License
In order to use the software to connect to XCP / A2L (ASAM Standard) based ECUs, a separate license is required. In order to use XCP features you do not also need a license to support GEMS ECUs.
If you would like to purchase an XCP license, please contact GEMS.

Tip
You can use the same license key twice so that you can have a copy of GWv4 activated on both your laptop and your desktop PC at the same time.
Offline Activation
If you are having issues connecting to our license server (it may be blocked by some network firewall software), click ‘Activate Offline’. Your machine key will be shown. Contact GEMS with your machine key and your license key - we’ll be able to provide you with a unlock code. Enter the code in the Unlock Code box and click ‘Activate’.
Moving a License
Once activated your license is locked to the computer it was first activated on. If you wish to move your license, you must first de-activate your license on your current computer before activating it on a new one.
To do this select the Deactivate License from the Licenses window. On confirmation, the license will be removed from the current computer. If your computer has been damaged, lost or stolen, please contact our support team via tech.support@gems.co.uk with your license key.
