Installing your license key
When you purchase a license key from JSCAPE or an authorized distributor, you will receive a confirmation e-mail containing your license key. This is a non-expiring license key and may be used for redistributing the licensed components as part of your application. If you have downloaded an evaluation version then you may use the evaluation license key provided. The evaluation license key is valid only for 30 days.
