In my recent post, I’ve touched upon the .NET feature in Windows. It is necessary for running many software in Windows, but it is disabled by default. If you try to require some software or app which requires .NET Framework 3.5, you might have faced the following message:
Now to enable it, you have to move to Windows Feature. This can be accessed via Control Panel > Programs and Features. If you don’t have a strong internet connection on your system, the download of required files may take a bit long time, and thus overall process becomes too lengthy.
Many users also reported me that they received Error 0x800f0906 when they checked the first option in the above image and then pressed on OK. Also if you try to download the full setup of .NET, it is 291 MB in size, and you will obviously need a fast connection to do it quickly.
Enable .NET Framework 3.5.1 on Windows
1. Open the .iso file of Windows 8 CP with a compression / decompression software like 7-Zip. Open the Sources folder and find sxs folder. Now copy this folder to the following location:
C:\Temp
2. Next, run the Command Prompt as administrator, and type the following command:
dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:\temp\sxs /LimitAccess
That’s it!
Now reboot and check the Windows Feature window again. You’ll see the first option is automatically checked. You will now also be able to run software or app which requires .NET (like AutoCAD. etc.), without any problems.
awesome
i log into windows 8 with built-in administrator account but i can’t run metro apps. can you help me?
Is your UAC Settings are adjusted to always notify level?
Because metro-apps doesn’t run without UAC permissions.
Thanks Kapil!!! Now I My old programs works… Great tutorial… any way this problem has already been solved in developer preview version. Thanks… 🙂
^^ Glad to hear that things worked for you 🙂
Yes, UAC are adjusted to always notify level… but when click on metro-tiles show message that “you must sign-in with another account and try again.”
When i login with a standard user, i can access to metro apps. but when login with administrator built-in account i can’t use metro apps.
But i got an error like this………….

The source files could not be downloaded.
Use the /source option to specify the location of the files that are required to restore the feature. The file location should be either the root dire
ctory of a mounted image or a component store that has the Windows Side-by-Side directory as an immediate subfolder.
The DISM log file can be found at C:WindowsLogsDISMdism.log
It seems that your .iso file is corrupted.
Re-download the .iso file from https://www.thewindowsclub.com/download-windows-8-consumer-preview-beta and try again. It should work on.
However I got the same error you are saying with these commands:
dism.exe /online /enable-feature /featurename:NetFX3 /Source:d:sourcessxs
dism.exe /online /enable-feature /featurename:NetFX3 /Source:d:sourcessxs /LimitAccess
But this procedure works for me……….
”
Update: Here is how to enable .Net 3.5.1 on offline systems.
All you need is windows 8 CP installation media,
First of all create “net35? folder in C drive.
Now open command prompt using Win +R, type and execute the following
command line
xcopy H:sourcessxs*.* c:net35 /s
where H is DVD drive, it takes sometime for all files to copied you need to be
patient.
After all files are copied open command prompt with admin privileges and
type and execute following command line
Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:net35
/LimitAccess ”
But, i want to know is, What is the difference between these two?
it says…..”Error 14028
A component’s file does not match the verification information present in the component manifest”
Can u help me?
Thank you. This really worked for me.
Thanks U , Worked Here . .
Can someone upload just the SXS folder, please?
for 64-bit system? I installed by Setup so I don’t have the iso file with Windows 8.

Hi Kapil,
I have installed .NET 3.5 Framework cause I couldn’t use Nitro PDF or IDM. I don’t have iso of Windows 8 or 8.1 (I’m running on 8.1) Is there anyway I can use the abovementioned programs without any hassle?
Please help me
Reviving a dead thread because it’s still an issue today.
I think Udiee is saying all three are causing errors.
My spacing is correct, and I’m getting the following:

I haven’t found a solution yet, but since the original author is probably offering that they’re getting all three errors, I believe your response about checking whitespace is misplaced.
In my case, it certainly is. Machine is recently reinstalled on a new SSD, I don’t have any recollection of how I originally got it to work. No useful information on what’s actually broken, either.
I did remove my WSUS configuration so Windows Update runs from the Microsoft servers, to no avail. Something to try, though.
Hi, It worked for me in Win 8.1.
not work for me
i cant enable it with every ways
please help me d ont work for me say it error 87 and the log file can t be found at windowslogdismdism.log
Error: 14003
The referenced assembly is not installed on your system.
The question here is this. Why on earth would stupid giant company like Microsoft create a Windows without this software enabled?
