Steema Central

Hi,

I am using TChart version 4.0.2011.2083.

It works just fine. However one of my customer is getting a strange error when trying to open a window that has a TChart on it.
The error is: "An instance of type "Steema.TeeChart.Chart" was being created, and a valid license could not be granted fro the type "steema.teechart.chart, contact the manufacturer of the component for more information.

What do I do here?

Regards Torben

Hi Torben,

This error message indicates that probably your application was not correctly complied with the TeeChart license as an embedded resource as explained in tutorial 17. To check if the developer license is correctly installed in the development machine please follow the steps described here and, if necessary, here. If the license is correctly compile into the application you should not get this error when deploying the application.

If this doesn't help don't hesitate to let us know.

Thanks, that was just the problem.
Due to a bug in VS2012, I made the msi on a different PC that has a old version of TChart installed.

The problem is solved now
