.net 3.0 problem

trying to install gfwl and got error message couldn't install .net 3.xxwhatever and to go to turn windows features on. I did that it and it failed half way (or so) and forced me to restart computer. Apon restarting screen came up and said update failed reverting then restarted itself again. Now there is no .net anyting in turn features on or off at all. It is completely missing. Please advise if anyone knows what to do. Thank you.

If you have a windows CD (or an ISO) try doing an offline DISM install.

Launch an elevated command prompt by search for cmd. Right click the command prompt search result and click run as administrator.
Put in your windows DVD (or mount your ISO) and type the following exactly


This is assuming your DVD or ISO is listed as your D drive, if it is not, change the source letter. The spacing in this command looks weird but it is correct, make sure that you have it as it's listed here.
