I have included a link
to our system requirements page that gives an overview of the system requirements and hardware requirements needed to run Sitefniity. There are no other requirements other than the ones listed on the page to run Sitefinity. The version of the controls for Sitefinity 3 is from 2010. There haven`t been more releases of Sitefinity 3 since then, you want to use newer version of Telerik.Web.UI.dll use newer .dll and reference it with binding redirect
If you have any other questions, please let us know.
