When you [download a .zip containing all binaries](https://www.telerik.com/products/winforms/documentation/installation-and-upgrades/download-product-files) for a specific version from your account, you need to replace the already existing assemblies in your project. Follow the steps:

1. Unzip the downloaded archive.

2. Select your project in Visual Studio >> Solution Explorer and expand the *References* section.
