I just installed 2009 Q1 and now most of my Design-Time controls do not render and display an error message as follows:

An unhandled exception has occurred.
Could not load file or assembly 'Telerik.Web.UI, Version 2009.1.402.35, Culture=neutral,...

I have added a reference in my Bin directory for the new Telerik.Web.UI.dll and the controls will render in Runtime, at least the ones I have tested.

One more piece of information I forgot to mention. Some controls, such as  Rad Upload and RadRotator DO render in design-time, but ScriptManager, RadCalendar, RadTabStrip,RadMenu will not

After reading some other posts on this subject, I have modified my web.config as shown below, but it has not solved my issues:

        <add path="Telerik.Web.UI.WebResource.axd" verb="*" type="Telerik.Web.UI.WebResource, Telerik.Web.UI, Version=2009.1.402.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false"/> 
            <add path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler, Telerik.Web.UI, Version=2009.1.402.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" /> 
            <add path="Telerik.Web.UI.SpellCheckHandler.axd" verb="*" type="Telerik.Web.UI.SpellCheckHandler, Telerik.Web.UI, Version=2009.1.402.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />

Thanks, but no. Actually, I tried that. I ran the .exe installer twice (after removing everything/uninstall) and NOTHING WORKED. Late last night, after over 8 hours of struggling to get this to work, I tried installing the Telerik.Web.UI.dll into the GAC (along WITH the Telerik.Web.Design.dll). Lo and behold, now all of my design time controls render properly.

For some reason, on my maching, the Telerik.Web.Design.dll HAS NO EFFECT on how the controls render at design time.

And yes, I checked all through the day to make sure the Telerik.Web.Design.dlls were installed in the GAC.

So, at least in MY case, your installer did not work.
