Solved Installing .net framework 3.5 with Dism command failed

[asma]

I want to install .net framework 3.5 I tried everything but still can't install it I used this command "dism /online /enable-feature /featurename:NetFx3 /All /Source:C:\sxs /LimitAccess " but this didn't give me any result and didn't show any error !!

Are you using install media such as an USB or DVD?

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:f:\sources\sxs

The letter after /Source: should be the drive letter of your install media(a windows 8 or 8.1 ISO) in this case my USB

Also the commands are letter case sensitive and spacing is important so open Notepad copy & paste my command in, change drive letter to yours, save, for future use, copy & paste in an Admin command prompt.

I solved the problem, the problem was caused by the antivirus, I uninstalled the antivirus and it works I finally installed .net framework 3.5
Thank you for your help.

You're welcome. I had/have this same problem when clean installing Win10 preview(.NET 3.5 isn't on by default) and need it for my USB mobile broadband software, so I have the above on a thumbdrive to remind me.
