Hi,
if a windows feature is in Install State removed, in this example the .NET Framework on Server 2012 R2.
PS C:\> Get-WindowsFeature *net*
Display Name Name Install State
------------ ---- -------------
.....
[ ] ASP.NET 3.5 Web-Asp-Net Available
[ ] ASP.NET 4.5 Web-Asp-Net45 Available
[ ] .NET Framework 3.5 Features NET-Framework-Features Available
[ ] .NET Framework 3.5 (inc....) NET-Framework-Core Removed
[ ] HTTP Activation NET-HTTP-Activation Available
[ ] Non-HTTP Activation NET-Non-HTTP-Activ Available
....
and if you try to install you’ll get an error message:
PS C:\> Install-WindowsFeature NET-Framework-Core
Install-WindowsFeature : The request to add or remove features on the specified server failed.
Installation of one or more roles, role services, or features failed.
The source files could not be downloaded.
Use the "source" option to specify the location
of the files that are required to restore the feature. For more
information on specifying a source location, see http://go.microsoft.com/fwlink/?LinkId=243077.

False No Failed {}
This occurs because the installation sources are not found respective the payload are removed from installation image install.wim.
The Solution is to install the missing features with Windows Update or if you have no internet connection to tell “Install-WindowsFeature” where the Windows sources are located.
Insert your Windows installation DVD or, if you are in a virtual environment, mount the dvd iso file. In this example the DVD is at drive Z:
PS C:\> dir z:
Directory: Z:\

Install the missing feature by specifing the DVD \sources\sxs folder as source:
PS C:\> Install-WindowsFeature NET-Framework-Core -Source Z:\sources\sxs

Thats it.
In Windows 8.x you have to use
PS C:\> Get-WindowsOptionalFeature -Online PS C:\> Enable-WindowsOptionalFeature -All -LimitAccess -online -FeatureName NetFx3 -Source D:\sources\sxs
instead of Get-WindowsFeature and Install-WindowsFeature.
If the error “The source file could not found. 0x800f081f” occurs, %SYSTEMROOT%\Logs\CBS\CBS.log contains CBS_E_SOURCE_MISSING errors: Uninstall all .NET releated Hotfixes:
