Steema Central

We have a problem with deployment of TChart after upgrading to 1.1.2004.16592

We get an exception
Exception: 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 of the component for more information.

Occured in: System.ComponentModel.License Validate(System.Type, System.Object)

Stack info:
at System.ComponentModel.LicenseManager.Validate(Type type, Object instance)

at Steema.TeeChart.Chart..ctor()

at Steema.TeeChart.TChart..ctor()


This happens both when building using the development version (on te computer where the development version is installaed) or distribution (no development license)

We have a special build server where all the products are built. The product built there gives an exception. We tried to install development version there, but that does not help. The only thing wich helps is running the reg file from your web site on the computer where the program is deployed - but this is not the way,I presume.

What should we do? - it is critical for the release of our product.

Hi Natalia,

Could you please read Tutorial 17 - Designtime, Runtime and License Requirements? Here it is explained how TeeChart's license control system works. You'll find the tutorials at TeeChart's program group.
