The following topic describes the installation packages for the Telerik UI for WPF and for the Demos solution.
Each installation package comes in three types:
MSI file for automatic installation.
ZIP file for manual (advanced) installation.
DLL files only (a.k.a. HOTFIX).
WPF Demos application comes in a zip package which you can extract on your machine.
The MSI files are intended for easy and automatic installation of a product. It installs the controls on your computer in a folder in your Program Files named Progress, and automatically creates the necessary virtual folders and projects.

If you already have Telerik UI installed from a MSI, you can safely install an updated version - the installer will keep your existing installation. The new files will be placed in a separate folder and the new installation does not damage the common installer files.
The ZIP is used to manual (advanced) installs and for upgrading/updating purposes.

DLL Files Only are used for updating/upgrading a product to a newer version. This is a bare-bones upgrade option for the Telerik UI controls. The hotfix contains only those files that you need to replace in your project to upgrade to the new version.
For more information about how to use HOTFIX DLL Files, read here.
The latest MSI and ZIP packages available for download already have all updates/HOTFIXES applied. There is no need to update them further.
The Demos Application ZIP package does not include the Telerik assemblies, so in order to build the Demos solution, you should have the latest UI for WPF components installed on your machine and that the example projects reference these assemblies. The referenced Telerik assemblies in the Examples projects by default are taken from the Telerik WPF installation directory on your machine.
If you have multiple UI for WPF installations on your machine the projects might sometimes reference an older installed version of the components. In that case you can run the Upgrade Wizard to update the referenced assemblies to use the latest version of the components in the projects you need to run.
