Our company purchased the standard edition of Flowchart.NET a few days ago. However, I am facing this problem.

I can add the item on the toolbox in visual studio 2003, but when i try to create a flowchart on a winform, i get this error:

"An exception occured while trying to create an instance of MindFusion.FlowChartX.FlowChart. The exception was "Couldn't get design time license for "MindFusion.FlowChartX.FlowChart".


I have practically tried everything, i tried adding it separately to references tree, but it didn't work.

From time to time I also get the following error:

"Request for the permission of type System.Security.Permissions.RegistryPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed"

We use .NET 1.1 and C#.

Thank you for your time.

The design-time key is read from the registry, so if FlowChart.NET does not have a CAS RegistryPermission, you won't be able to use the control. Make sure your logon account has permissions to read the following registry ky:

HKEY_LOCAL_MACHINE\SOFTWARE\MindFusion Limited\ComponentLicenses

Also try assigning the Everything permission set to the Flowchart.NET assembly, from our experience the FullTrust set seems more restricted.
