Are free licenses provided for demo or test servers?
The COZYROC SSIS+ Suite is free to download and use in a development or test environment. By definition, execution from Visual Studio is considered a development or test environment.
A purchased license key is required once you plan to schedule the
execution of packages through the SQL Server Job Agent. For demo purposes, for a test environment, or for a migration situation, a trial license key is available, which can be used for 30 days. To use the trial license key so that packages can be executed under the SQL Server Job Agent, open the COZYROC license application and enter the word “TRIAL” for the Licensee Identifier within the License Application.
If the license application immediately indicates that the key is expired, please see the article:

Note that the trial key gives you the same suite and capabilities that you will have once you purchase license keys. The only difference is that you are limited to 30 days with the trial key.
