Had a go to meeting to discuss Telerik tools integration with Desislava Nikolo and another consultant. They acknowledged this issue and resolved to contact me after the meeting to provide a fix. Basically, from the Telerik Tab in the IDE 2010, I am unable to load any of the RAD tools for development.
Hi, In most cases this issue could occur in case of manually installed Telerik web parts In the following section of our online help documentation you can find information on Upgrade and Removal procedures: http://www.telerik.com/help/aspnet-ajax/moss-installing_radeditor__radgrid_web_parts_on_sharepoint_2010.html We suggest removing the old Telerik web parts and then installing the latest version.
