[Fix] 0x800F0906 and 0x800F081F Error Messages While Installing .NET Framework 3.5 in Windows 8/8.1

You might be aware of the fact that Windows 8 and Windows 8.1 operating systems don't come with Microsoft .NET Framework 3.5 installed. But there are many 3rd party software programs which require .NET Framework 3.5 in your system. In such cases you need to install the .NET Framework 3.5 version in Windows 8/8.1 manually.

There are 2 ways to install .NET Framework 3.5 in Windows 8/8.1:

• Online Install
• Offline Install

In Online Install method, you install .NET Framework 3.5 using Control Panel -> Programs and Features -> Turn Windows features on or off option. In this method, Windows first downloads the setup files of .NET Framework 3.5 from Internet and then installs it in your computer system.

In Offline Install method, you use a built-in command to install .NET Framework 3.5 directly using Windows setup disc without requiring Internet connection as mentioned here. You can also useMicrosoft .NET Framework 3.5 Offline Installer to automatically install .NET Framework 3.5 offline in Windows 8/8.1.

PROBLEM DESCRIPTION:

Recently we have received many comments and emails from our readers regarding a few error messages while installing .NET Framework 3.5 in Windows 8/8.1. Whenever users try to install .NET Framework 3.5 in Windows 8/8.1, they receive following error messages:

Error: 0x800F081F
The source files could not be found.

OR

Error: 0x800F0906
The source files could not be downloaded.
OR
Windows couldn't connect to the Internet to download necessary files. Make sure that you're connected to the Internet and click "Retry" to try again.

It doesn't matter whether they try online method or offline method, the same error messages and codes are shown by Windows.

PROBLEM REASON:

Actually these error messages are coming due to following 3 updates recently released by Microsoft for .NET Framework 3.5:

• KB2966826
• KB2966827
• KB2966828

Above mentioned updates are security updates for .NET Framework 3.5 in Windows 8.1 and Windows Server 2012 R2. These updates are applied via Windows Update regardless of whether you have .NET Framework 3.5 enabled or not. If these updates are installed in your system and you try to install .NET Framework 3.5, you'll receive 0x800F0906 and 0x800F081F error messages.

PROBLEM SOLUTION:

To fix this problem, you just need to uninstall these security updates from your system and then install .NET Framework 3.5. After successfully installing Framework version, you can reinstall the security updates without any problem.

So if you are also facing this problem, just follow these simple steps to fix the issue:

1. Open Control Panel, click on Programs and Features icon and then click on View installed updates link present in the left sidebar.

2. Now scroll down a little and look for following updates:

• KB2966826
• KB2966827
• KB2966828

3. Once you find the updates, right-click on each update and select Uninstall option. Alternatively, you can double-click on the updates to directly uninstall them or click on Uninstall button present in the toolbar.

4. After uninstalling the updates, try to install .NET Framework 3.5 again using any method and this time it should install without any problem.

After installing NET Framework 3.5, you can reinstall the security updates using Windows Update.

We know that Windows 8 and later operating systems don't come with Microsoft .NET Framework 3.5 but there are many 3rd party software programs which require .NET Framework 3.5 installed in Windows. So people use online or offline methods to install .NET Framework 3.5 in Windows 8 or later as given in following tutorials:

• How to Install .NET Framework 3.5 Offline in Windows 8 and Later without Internet Connection?
• Download Microsoft .NET Framework 3.5 Offline Installer for Windows 8 and Later

But there are a few people who have faced problems while installing .NET Framework 3.5. When they try to install it, they receive error messages such as the source files could not be found or downloaded, etc. These error messages contain different error codes such as 0x800F081F or 0x800F0906.

To fix these problems, we posted a troubleshooting article which allows you to install .NET Framework 3.5 in Windows 8 and later without receiving any error messages:

• [Fix] 0x800F0906/81F Errors While Installing .NET Framework 3.5 in Windows 8 and Later

The above mentioned guide helped a lot of people and fixed the error messages but still there were a few people who were not able to install .NET Framework 3.5 in Windows 8 and later. Then an AskVG reader Patrik posted a different solution which worked for those people.

Patrik: I have three Surface Pro 3 with Windows Pro 8.1 that have the same issue. .NET Framework 3.5 will not install. I've tried both via DISM, Programs and Features and via full install setup. I have tried to uninstall every single Windows update on the machine and then install via DISM, but that didn't help either. I even tried to install all three KB-updates (KB2966826-8) to see if I can uninstall them to get rid of potential dll-files that could be interfere with the .Net 3.5 setup. So I then decided to wipe it clean via Windows own restore system guide. But it didn't even work after I have done a clean Windows install. Immediately after Windows installed I tried to enable the .NET 3.5 feature, and of course DISM didn't work either. I have called MS support to get some assistance, but I guess they will call back in a few days or so. Finally, I have solved the issue after many hours. I found a setting in the local computer policy.

Today in this article, we are going to share the solution given by our reader Patrik so that all Windows 8 and later users can install .NET Framework 3.5 without any problem.

This solution should work for all devices whether its a Desktop PC, laptop or Surface tablet running on Windows 8, Windows 8.1 or Windows 10 operating systems.

If you are also facing problems while installing .NET Framework 3.5 in Windows 8 or later, check out following method to fix the issue:

1. Type gpedit.msc in RUN or Start search box and press Enter. It'll open Group Policy Editor.

2. Now go to:

Computer Configuration -> Administrative Templates -> System

3. In right-side pane, look for "Specify settings for optional component installation and component repair" option.

4. The option would be set to Not Configured. Double-click on it, set it to Enabled and enable "Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS)" option.

That's it. Now try to install .NET Framework 3.5 again using Control Panel -> Programs and Features or by using DISM command and now you'll not face any problem.
