PC Developer license
A single PC developer license allows the software developer(s) to use ImageKit.NET on only one PC.
The 3 PC developer license allows the software developer(s) to use ImageKit.NET on up to 3 PCs.
The 5 PC developer license allows the software developer(s) to use ImageKit.NET on up to 5 PCs.
The 10 PC developer license allows the software developer(s) to use ImageKit.NET on up to 10 PCs.
The 20 PC developer license allows the software developer(s) to use ImageKit.NET on up to 20 PCs.
The 50 PC developer license allows the software developer(s) to use ImageKit.NET on up to 50 PCs.

The ImageKit.NET license is tied to the PC and not to the developer. If a single license is installed on a PC and two developers use that machine, that is fine. If one person wants to use the ImageKit.NET on 2 PCs, he or she will need two separate PC Developer licenses.

After the ImageKit.NET is installed on a PC, the license must be activated. The ImageKit.NET has a built in license activation program that activates the license After installation, the activation program runs and asks the user for two pieces of information:
1. the Serial number of the ImageKit.NET
2. the Product id

Run-time royalty free for use in Windows Forms applications.

Server Runtime License
ImageKit.NET now has Server runtime licenses. If the customer runs an ImageKit.Net application on a server, then they need to have a Server runtime license for each server running applications. (A server runtime license is not required to deploy applications via ClickOnce deployment as these applications do not run on the server)

Notes: To purchase a server runtime license the customer must already have at least 1 PC Developer license.
