Dot Net Framework 3.5 Not Installing on Windows 8? Fix it Now!

.net 3.5

You may face a common problem while using Windows 8. Microsoft .Net Framework 3.5 is not installed with Windows 8. And several programs may ask you install this. And you can't install this from your PC. It will ask you to connect to the net and use Windows Update. 

By default Windows 8 comes with .Net Framework 4.5 and it doesn't include 3.5. When you try to install .Net 3.5 that you previously downloaded from web the you will see the following message. 

App requires .net ramework 3.5

And you will get the same message while installing some some programs that is developed using .Net 3.5 platform. And you will not able to run those programs on your PC! This is a very bad job by Microsoft. A great trouble for Windows 8 users. 

But today you will get the solution. You've install this using command line. I mean you have to use Command Prompt. And surprisingly you Windows 8 DVD includes the .Net Framework 3.5! 

Method 1 (Offline Installation using cmd):
  1. Enter your Windows 8 Installation Disk on DVD Drive.
  2. Now run Command Prompt as Administrator. (Hint: Start > Type cmd > Now right click on Command Prompt and hit on Run as Administrator from the bottom)
  3. Now copy the following command and paste it in the command prompt window. Or type the following line in command prompt. Press Enter (To paste the command in command prompt, click the right button of mouse and select paste)
  4. Now .Net Framework will be installed within few minutes. 

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

Remember: h is the drive letter of DVD drive. Change it with your DVD drive letter. 

Method 2 (Online Method using Windows Update): 

If you follow all the instructions of method 1 you will be able to install .net 3.5 properly. But if there is any problem for example- you don't have DVD drive, or your Windows DVD doesn't contain it then you can install it directly from Windows Update option. More or less you've to download 200 MB data from internet. 

Follow the instruction below: 
Control Panel > Programs and Features > Turn Windows Features on or off > Mark the option .NET Framework 3.5 (includes .NET 2.0 and 3.0) > OK. 

Now you will see a window like the image above. Hit on Install This Feature. And make sure you're connected to the net. That's it.  

Secret Tips: If you upgrade to Windows 8 from Windows 7, then you get .Net Framework 3.5 automatically enabled !!

Installing a Windows language pack on Windows 8 before installing the .NET Framework 3.5 will cause the .NET Framework 3.5 installation to fail. Install the .NET Framework 3.5 before installing any Windows language packs.

  15. Hi,

    I am not able to activate w8 Enterprise X64. When i click on the activator it opens cmd window and closes my explorer. Then there is no sign of activation.

    1. Actually this is about .Net Framework. You should write this on Windows 8 Activator related post.

      By the way, some of the users reported problems like you. But we never experienced such problems in our test projects. Maybe you're using any third party antivirus. Remove it first. Then try again.

  16. hey window features .net framewok3.5 is not installing plz help

  17. Boss pls locate the correct location path from pendrive
    pendrive name:J

    then checkout it contains the source folder>>>( j:\sources\sxs)

  23. Hmm I followed every step carefully and I'm still encountering a problem. It stops at 65.8% with the error 0x800f081f and tells me that the source files could not be found.

  24. Hey, I followed your steps using a windows 8 disk and i'm getting a error 11. How do I fix this?

    1. Make sure you've followed the steps properly. And also read the reasons for failure. Read the comments too.

      If you fail, then install Windows 8 from different disk, or try installing .net with a new disk.

  25. thank you so much it worked for me...

  26. Thankyou so much i will also share this on my blog and give credits to munnamark

  27. A very big Help Mr. Abdur Rahaman, it works.. Thank you very much sir for sharing your ideas..

  28. How to type h comnand from drive

    1. Actually I can't understand your question. You can contact me personally.

  29. Replies
    1. Write in details. Or chat with me via Google +

    2. I have tried every step of every thread there is and the only close clue I get is that some "Language Pack" intefers with the availability of installing .NET 2.0.... tried for countless hours...:
      The answer with the language stamement is far down..

    3. Re install your Windows. Which version it is?

    4. So I cant just find the file which is not working for me and input it somehow? I'm missing Microsoft.Build.Utilities v2.0.0.0 for a compiles through that...8.1 Pro

    5. The best solution is re-installing windows. After installing the Windows, install .net 3.5 immediately. Make sure Windows Disk is inserted. And don't change your language settings before installing 3.5. 64 bit windows often have this problem.
