In order to have Telerik® UI for ASP.NET AJAX running, you will need to have .NET 4.x+ installed on your development/production machine.
The MSI files are intended for easy and automatic installation of a product. The MSI installs the suite on your computer to a folder named Telerik in your Program Files, automatically creating the necessary virtual folders and projects. Additionally, it installs the help file(s) in the VS.NET IDE and in your local copy of MSDN, if you have one installed.
To install Telerik UI for ASP.NET on your machine from the Windows Installer MSI file, follow the instructions below:
Log into your Telerik account and click on Downloads from the top menu.
On the loaded page choose from your purchased products or trial downloads Telerik® UI for ASP.NET AJAX, and click on it.
Download the Automatic installation (MSI) file.
Once the download completes, run the MSI file and follow the instructions. On a 32bit machine the wizard will install the Telerik® UI for ASP.NET AJAX component in the following folder unless you specify otherwise: C:\Program Files\Progress\ and the path is C:\Program Files (x86)\Progress\ for a 64bit machine.
The latest package available for download already has all updates/HOTFIXES applied. There is no need to update it further.
The MSI installation will not overwrite previous Telerik® UI for ASP.NET AJAX installations, unless it is of the same version.
The installation paths prior R3 2017 are C:\Program Files\Telerik\ and C:\Program Files (x86)\Telerik\.
From the the Resources section of same page you can also download the MSI installation for the examples of the Telerik® UI for ASP.NET AJAX. Once you install them on your machine, you can launch the Live Demos in either of the following ways:
Using the Start Menu programs: open Telerik -> Live Examples - UI for ASP.NET AJAX
Using Windows Explorer: Navigate to the Telerik control Installation Folder (typically C:\Program Files\Progress\UI for ASP.NET AJAX RX YYYY\Live Demos) and double-click the StartExamples.exe file
Load the Live Examples solution to your Visual Studio and start the project (F5). The fastest way to load the solution is using the Start Menu: Telerik -> UI for ASP.NET AJAX RX YYYY -> Open Sample Web Site in Visual Studio. Visual Studio will start the Live Demos locally using the integrated ASP.NET Development Server.
