This how-to guide will help you to enable .NET Framework 3.5 on Windows 10 using the Deployment Image Servicing and Management tool.

.NET Framework is the basic need for some apps you’ll use on your Windows 10 machine. Since these apps are written/coded with .NET language, hence you additionally need to enable .NET framework to run them. This framework is not enabled by default in Windows since the OS uses C, C++, C#, V# etc. language packages. So when you run any app requiring .NET Framework, you’ll receive this window:

An app on your PC needs the following Windows feature:

.NET Framework 3.5 (includes .NET 2.0 and 3.0)

How To Enable .NET Framework 3.0 On Windows 10

Thus to enable .NET framework, you click or tap Download and install this feature in above shown window. But if you notice this window carefully, there is a message at top that you’re on Metered Connection and will require additional charges for download. Also, enabling .NET framework is better processed by Deployment Image Servicing and Management Tool aka DISM tool. If you have Windows 10 ISO file with you, which you used for installation of the OS, you can use it to enable .NET framework in few seconds.

Here is the how-to part:

How To Enable .NET Framework 3.5 On Windows 10

1. Create a temporary folder under system root drive directory (i.e. if Windows is installed on C: drive, then create Temp folder such that its can be located at C:\Temp).

2. Locate the Windows 10 ISO file in File Explorer, right click on it and select Mount. Reboot the machine, you’ll find that ISO file is mounted to DVD drive with temporary drive letter. You can also or alternatively plug Windows 10 installation bootable USB like the way I did. Open this drive and open Sources folder. Copy the sxs folder now to temporary folder you’ve create in step 1.

3. Now search for powershell in Windows and spot Windows PowerShell from search results. Right click on it and select Run as administrator.

4. Finally, in the administrative or elevated Windows PowerShell, type following command and press Enter key:

dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:\temp\sxs /LimitAccess

* Substitute c:\temp with the temporary folder location we created in step 1.

How To Enable .NET Framework 3.0 On Windows 10

In few seconds, you’ll get The operation completed successfully message, which indicates the .NET Framework has been enabled on your system.

Run .NET Framework Repair Tool in case if you’ve any issue with .NET Framework.

That’s it! See this fix if you receive “The referenced assembly is not installed on your system” error while enabling .NET Framework.

  • Another easyer method:Control Panel classic—-Programs&Features—-Turn Windows Features on or off(on the left side);on the right side a list will appear—tick the box,which refer to Net Framework 3.5.Windows will download&install the requested features

    ^^ Yeah, its also a good alternative if you have fast web connectivity :)

  • Yes,a decent internet connection is needed,because windows need via windows updates to download requested installer whose size is something like between 200 MB-250 MB.

  • Hi Kapil,
    practically my last chance is, when I call you with the issue regarding my system and ask your help.
    My system is W10Pro(1834) with two uncommon ‘features’:
    – it is installed (and boots from) a VHD
    – I use directory junctions for the followings:
    because of theirs extremely aggressive demand for storage capacity. Linked directories are placed to a separate physical drive (not just into a different partition).
    Well, I know, that MS does not support (why?) update to VHDs. And it seems that the situation is the same for enabling .net feature, because I tried all methods, what I found for installing .net3.5, but the latest achievable result was a 0x80070011 error: “the installer cannot relocate the directory”. I was not able to repair this error with any of different ways usually suggested to repair the widows update error issue.

    So I ask for your kind opinion, whether am I right, and enabling windows feature is neither supported on VHDs. BUT I hope, I’m wrong and you can suggest a solution. Thanks!

  • This did not work for me. I got Error: 2 (The system cannot find the file specified). This is a pretty old post, so I don’t expect much response.

  • Took about 50 mins from start to finish –did not need to reboot after mounting folder .
    Bit following the rest of instructions worked great –Thank you

  • Kapil Arya

    ^^ Glad it helped you!

  • Tried lots of tut to fix my problem. so glad it worked with my win 8.1. thanks a lot!

  • Kapil Arya

    ^^ Have you tried steps mentioned in article? Let me know if any step didn’t worked for you.
