Thank you for contacting us.
Please, follow this link to get to the 'Product versions' page: http://www.telerik.com/account/your-products/product-versions.aspx?pid=571
In order to download previous versions you need to login to your Telerik account and go to: "Manage products", and click on the "Download Installer and Other Resources" button next to the RadControls for Silverlight. There you will see a link: "Download also: Older versions"
Do not hesitate to come back to me if you need any further assistance.
All the best,
