    We are currently in the process of upgrading a number of site collections from SharePoint 2010 to SharePoint 2013.
    A few of these site collections uses Telerik Components, for example Telerik RadEditor.

    If we open one of these sites we get the following error message:

    Could not load file or assembly 'RadEditorSharePoint, Version=, Culture=neutral, PublicKeyToken=1f131a624888eeed' or one of its dependencies. The system cannot find the file specified.

    Our plan is to not do a visual upgrade but instead keep running the sites in SP2010 UI mode whenever possible. We're not sure if this is supported for the Telerik SharePoint 2013 web parts?
    What would be the best way to handle this? We assume we have to install the 2013 version of the Telerik components.

    We tried installing Telerik_Web_Parts_For_Sharepoint2013_2015_2_826_Trial.msi but that doesn't seem to work. We still get the same error message.

    Any help or suggestions would be much appreciated.

    Hello Martin,

    I suspect that the described error appears because the RadEditor Web Part for SharePoint has not been upgraded properly. Please, examine this help article ( and make sure that there are binding redirects for the new, upgraded assemblies, so that the migrated web parts to be successfully redirected. 

    If you want to get updates on new releases, tips and tricks and sneak peeks at our product labs directly from the developers working on the RadControls for ASP.NET AJAX, subscribe to their blog feed now.
