(D:) 2, then right click on the bottom left corner of the start menu (Win + X), select - command prompt (administrator) .3, then enter the following command: dism.exe /online /enable-feature /featurename:NetFX3 /Source:D:sourcessxs (Note: where D:sourcessxs is the location of the Win8 installation file) 4.
