Install IIS Web Platform Installer

Web Platform Installer discontinuation

The Web Platform Installer has been discontinued by Microsoft. The official support ended on 7/1/2022. As of 1/1/2023, the Web Platform Installer can no longer be downloaded from the Microsoft Download Center (https://blogs.iis.net/iisteam/web-platform-installer-end-of-support-feed).
This eliminates the need to install the AAR module and the URL Rewrite module via the Web Platform Installer.

Instead, download the AAR module and the URL Rewrite module directly from Microsoft and then install the modules. For a detailed description of this, see section Manually install ARR and URL Rewrite modules.

Install the IIS Web Platform Installer. The Web Platform Installer is software from Microsoft that is part of the IIS post installation. The Install IIS Web Platform Installer can then be used to install the ARR module and the URL Rewrite module in IIS. These are required to use IIS as a reverse proxy.
