The free version of ECO allows you to use up to 12 classes, no questions asked. You can deploy the application for personal or commercial use. If you need to use more than 12 classes you need to have a license.
Licenses for Eco for Visual Studio can be purchased at the capableobjects website. A license for Eco for RadStudio is included when you buy RadStudio 2007 Architect.
To install a new license, open the ECO aboutbox and klick the button "Enter License".
The license is stored on disk in the following folder:
Vista: C:\ProgramData\CapableObjects
Windows XP: C:\Documents and Settings\All Users\Application Data\CapableObjects
In designtime, a license will allow you to use the ECO designtime support with more than 12 classes. The aboutbox will indicate if ECO has detected the presence of a license or not.
In runtime, the ECO framework will load the license information from an embedded resource in your application. To get the license information embedded in the application, ECO adds a file called "licenses.licx" to your project. Your IDE will call an application called LC.exe (LicenseCompiler) when it tries to compile a project with a licx-file in it.
This file should contains a single line:
Eco.Handles.DefaultEcoSpace, Eco.Handles
Other third party components that use the same license mechanism will add additional lines to this file.
In build 4.0.0.2230 and later, the ECO license should be included in the project that contains the EcoSpace. Earlier builds looks for the license in the binary of the application (which means that you must include the licx file in the Winform/ASP/VCL/Server application). It is not enough to have a licx-file in the directory of your project, it must be included in the project.
To check if your binary really includes a license, you can inspect it with
Reflector
. Check the resource-section of your assembly/executable. It should contain a resource called "
EcoProject5.EcoSpace.dll.licenses
" (or something similar) and in the contents of the resource you should be able to see:

Note:
Some third party components seems to replace the contents of the licenses.licx-file rather than just append to it, so if you are using other components that use the licenses.licx-file for its license management, you may want to check if it still contains the line
User Comments
Dear Jonas,<br /><br />I used ECO, included in Codegear RAD Studio 2007 (Architect edition). Then I've decided to upgrade my ECO, uninstalled the default one and installed a new one, which has been downloaded from this site. Now I see, that ECO has a single developer license. I tried to input a serial number, but it is no way to do it in RAD Studio, because "about ECO" window just shows me information about it and three buttons:<br />1) Copy build numbe<br />2) Check for updates<br />3) Close<br /><br />How can I input a serial number or license file now?<br /><br />Thanks in advance,<br />Andrey Andreev
