Today we upgraded one of our client's site from DNN 4.9.x to 5.04.01 and encountered the following error:

Could not load file or assembly 'Telerik.Web.UI' 


The file named “Telerik.Web.UI” is missing from the Bin directory.


Download the full install version of DNN and copy the 'Telerik.Web.UI' from the bin directory over to your website's bin directory.
