"...a valid license could not be granted..." what

[Russ]

I am developing Windows application using VS 2008 in C#. If TeeChart is not used in the app, I can start the app on a PC by copying some files (.dll & .exe) and running the .exe. However, if TeeChart is used in the app, I will get a message like the following:

An instance of type 'Steema.TeeChart.Chart' was being created, and a valid license could not be granted for the type 'Steema.TeeChart.Chart'. Please contact the manufacturer fo the component for more information.

at System.ComponentModel.LicenseManager.Validate(Type type, Object instance)
at Steema.TeeChart.Chart.ctor()
at Steema.TeeChart.TChart.ctor()
......

What do I need to do in order to run the app including TeeChart without the above message?

Thanks,

Al

Thanks, Narcis, for the reply. I followed the thread and also "Tuturial 17 - Designtime Runtime and License Requirements" I overlooked earlier. My app creats TeeChart components at both design time and run time and involves both .dll and .exe. After editing some license files, it worked without that license problem.

Thanks,

Al
