We are evaluating whether to use Telerik to redesign a legacy web app written using an old version of Telerik.
After downloading Trial version on fresh install of windows, I can't add ajax control to form. `I am using visual studio 2019, this is the first version of Telerik installed on this computer. I just get the "Error Creating Control RadScriptManager1. They do show up in the toolbox so this surprises me.
Very latest version.

Could it be a license issue?
Hello Robert,
If the error is when the Design-time view is opened, then the issue should be a missing Telerik.Web.UI.Design.dll assembly reference. More on the topic can be found in this documentation article:
If the issue persists, please open an official support ticket with more details on your scenario and setup and we will be happy to help you resolve them.
Regards,
Peter Milchev
