My computer crashed so we had to rebuild it.  I downloaded the most recent telerik files that I had licenses to.

I have some sites that used the older versions.  

So when I opened them, I'm getting the error 
"Failed to create designer 'Telerik.Web.UI.xxx version 2011.1.519.35 etc"

how to I fix that?

Thank you.

Hello Lourdes,

The error you are currently facing indicates that there is a mismatch between the loaded dll assemblies and the ones that the project is initially build with . Please refer to the following topic where possible solutions to this problem are described:

I hope this will prove helpful.

All the best,
