If you purchase a single license, then you can install our product on one computer only. Please note you CANNOT transfer the license from one computer to another, unless the old computer will never be used in the future anymore (be abandoned).

If you want to install our product on multiple computers, you have the following 3 options:

1. Purchasing the number of licenses based on the quantity of the computers you want to install. We offer a volume discount if you purchase multiple licenses at the same time.
2. Purchase a site license so that you can install our software on an unlimited number of computers in your organization.
3. If you are a technician, and want to transfer the license from one computer to another freely, then you can purchase a technician license which allows you to do so.

Feel free to [contact us](https://www.datanumen.com/contact/) if you are interested in purchasing a site license or technician license.
