Hello,

In order to take care of this error you try the following:
◾Perform a manual upgrade procedure as described here:
http://docs.telerik.com/devtools/aspnet-ajax/installation/upgrading-instructions/upgrading-a-trial-to-a-developer-license-or-to-a-newer-version#manual-upgrade.
◾If you still get the "cannot load file or assembly" error, try the information from this section and see if it helps:
http://docs.telerik.com/devtools/aspnet-ajax/installation/upgrading-instructions/upgrading-a-trial-to-a-developer-license-or-to-a-newer-version#could-not-load-file-or-assembly-telerikwebui-after-upgrade.
