"Setup is unable to proceed due to the following error(s):This product requires Microsoft .Net Framework 4.5."

Step 1: Uninstalling .Net framework 4.5 from server manager.
=============================================
      We uninstalled .Net framework completely and we rebooted server. After rebooted server it was showing only cmd prompt. Even UI is not controlling through mouse or key board. After some google search we rolled back to server with some commands.
   1).  DISM.exe /online /enable-feature /all /featurename:NetFx4
   2). DISM.exe /online /enable-feature /all /featurename:MicrosoftWindowsPowerShell

Above two commands run with any error then reboot server using shutdown -r

once server got rebooted,then type PowerShell on Cmd prompt and run  GUI installation with following cmd.

  1). Install-WindowsFeature Server-Gui-Shell, Server-Gui-Mgmt-Infra

Reboot server with Shutdown -r.
