Thank you for you question.
The problem does not seem to be related to our controls. I do not have a clue why this is happening. Is your windows application referencing other dlls that are copied to the web.config assembly section upon building?
Additionally, please ask the person who purchased our controls in
your company to add you as a License Developer to the purchase. More in
License Developers you can find here: www.telerik.com/faq
. This will ensure that we will get the most of our support services.
All the best,
the Telerik team
