Upgrading assemblies after version upgrade

Hi

I have upgraded to 4.1 SP2 and am now getting below error on pages with custom widgets;

Could not load file or assembly 'Telerik.Web.UI, Version=2010.3.1109.40, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Where can I find the latest assemblies to start with and what are the simple steps to upgrade my project to the latest assemblies for my custom widgets?

Thanks

Regards

Hi

After rebuilding the project the error is changed to the one below. Any ideas?

Thanks

Regards

Hello,

Make sure that the dlls are in your bin folder.When you perform rebuild, the bin folder gets cleared. You can use _EmptyProject that is added with each installation to recover the missing dlls.
