Windows Server AppFabric: Intallation Skipped
Even after enabling the IIS Server role as described in the Microsoft Support Article, and running the Products Preparation Tool, you might get the error for App Fabric Cache installation. Inspite of running the Products Preapration Tool, the Windows Server AppFabric Installation is always skipped and cannot proceed further with SharePoint installation. To solve this manually install the App Fabric Cache using the following command in PowerShell.
$appfabric_setup = "<<Full Folder Path>>\WindowsServerAppFabricSetup_x64.exe"
& $appfabric_setup /i CacheClient","CachingService","CacheAdmin /gac
After manually installing the Window App Fabric Cache, run the products prepartion tool again which completes the pre-requisites installation successfully and you can continue with the SharePoint intallation.
