The easy way to install the DataEngine library is through the ComponentOneControlPanel application. There are two methods for installing DataEngine library using the ComponentOne ControlPanel : one is by using the "Install Selected Controls" option, and the other is by using the "Show Full Installer" option. To directly install the latest version of the library, use the "Install Selected Controls" option, and to install the specific version of the library, you can use the "Show Full Installer" option. In both the options, a trial version of the library is installed, which is valid for 30 days. You can easily extend the usage of ComponentOne controls/libraries beyond 30 days by activating the license using a serial key. The serial key can be purchased from the Sales team or Website.
