Hi Curtis,

In order to solve this issue you need to debug your application and put a proper debug point and see where the errors are coming, but seeing it from outside I think you have missed some of the Telerik references to your main project. Try to include the following in your main project and run again.

1. Telerik.WinControls.dll

2.Telerik.WinControls.RichTextBox.dll

3.Telerik.WinControls.SpellChecker.dll

4.Telerik.WinControls.UI.dll

5.TelerikCommon.dll

Including these files may solve the issue.
