One software license is required per user.
Runtime NOT Royalty free.

The PDF Library SDK is licensed as a Developer license, with requirements for internal runtime licenses and OEM distribution licenses.

A Developer License allows the deployment of the licensed software to one (1) client computer (for internal usage only). It does not include the right for access by concurrent users. A desktop computer is a computer that is designed for and is used by a single user.

An Internal Runtime License is required for each additional client/user within your organization.

To distribute the developed software outside your organization you will need an OEM License. Please contact sales@componentsource.com for a quote.
