Sitecore Quicktip: SIF Prerequisites.json Has Outdated File Links

When deploying Sitecore via the Sitecore Installation Framework (SIF), installing the prerequisites is critical. However, due to a few outdated file links, it will not execute properly and generate an error such as:

[-------- DownloadWebPlatformInstaller : DownloadFile ------------------------]
[DownloadWebPlatformInstaller]:[Download] https://download.microsoft.com/download/C/F/F/CFF3A0B8-99D4-41A2-AE1A-496C08BEB904/WebPlatformInstaller_amd64_en-US.msi => C:\Users\{Username}\AppData\Local\Temp\WebPlatformInstaller_amd64_en-US.msi

The outdated links are resolved in the SIF for Sitecore Version 10.1.1 (10.1 Update 1). Depending on your Sitecore version, you will need to update either the Web Platform Installer link or the link for the .NET Framework Download.
