License Activation

License activation is necessary to verify the authenticity of the serial key used to license the product. It also ensures that keys are only used to license a permitted number of machines. Activation is done with the MESCIUS License Manager .

Once you have downloaded and installed Spread for WPF as evaluation from the official website or through the NuGet gallery, a trial key is automatically installed on your machine. This trial key will expire in the next 30 days.

After the trial expires, if you still want to evaluate the controls, you can contact us to obtain an Extend Trial License. You may also choose to purchase a license and activate it with a valid serial key. For more information about current licensing prices, please check out our Spread.NET Pricing page.
