Q&A - Question License Exception Question FabD asked on September 09, 2016, keyword: Developer Kernel I'm trying the .NET SDK (trial version). I would like to add a TGIS_ViewerWnd inside a form using the form editor (C#). When I drag and drop the control from the toolbox into my form, I get this error message: System.ComponentModel.LicenseException: The TatukGIS component cannot be created because ithas not been activated.... However if I open a project from the Samples, I can run it without errors. Answers Tomasz Kosinski (TatukGIS) replied September 09, 2016 Please to try this: open VS "As Administrator", create a new NET3.5 project add TatukGIS assemblies to the tooolbox, place a TGIS_ViewerWnd control on the form, enter license details if/when you will be prompted, restart VS eventually restart computer.
