Hi Abdu Bukres,
We have two distributions for ASP.NET AJAX. The one is an msi file (Automatic installation) and the other one is a zip which contains folders with dll files, scripts and skins (Manual installation).
I am afraid you have downloaded the Manual installation. So if you want to use the installer for the ASP.NET AJAX please download the Automatic Installation
. Under the installation link it is written msi file, 176 MB.
I hope the information was helpful.
All the best,
the Telerik team
