after that, you need mount DVD install to you computer or if you
have ISO file,you can double click to mount to virtualdevice.note:
you must use same version of DVD or ISO with your OS version,
example, ifyou install 64bit version of Windows, you need 64bit
version of installer, not modify ISO all in one version(include
both x86 and x64 version of windows in 1 ISO file).if you use x64
(64 bit) version of windows and mount x86 (32bit) installer,
youwill get error during run following command.
in my case, I'm using DVD.after that, you run CMD as
administrator, by press Windows + X then press A or right click to
Windows icon.code:Dism /online /enable-feature /featurename:NetFx3
/All /Source:X:\sources\sxs /LimitAccess
replace X by name of DVD or virtual device. In my case device
name D, so i havethis code:Dism /online /enable-feature
/featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess
