Fixing Error Codes 0x800F0906 & 0x800F081F while Enabling .NET Framework 3.5

June 17, 2013 8:31 am \ 57 Comments \ by Ivor

A user of Windows 8(8.1) operating system occasionally comes across to the above noted error codes. These errors occur when Windows is unable to download the required files from Windows Update Server. A detailed clarification of .NET FRAMEWORK is indicated below to understand the overall phenomenon of Error Codes 0x800f0906 and 0x800f081f.

Prior to proceeding this piece for the solution, let be advised to first Scan and Fix your system’s concealed disorders which most probably is eliciting the inconsistencies:

Step 1 : Download Systimizer – PC Cleaner & Internet Booster (Works on Windows 10, 8, 7 & XP)
Step 2 : Click “Scan” to find system issues
Step 3 : Click “Fix” to repair all anomalies

Particular applications require a specified version of .NET Framework for assured compatibility. Windows 8 comes with an incorporated version 4.5, although, there are certain applications necessitating version 3.5. It is to be noted that in Windows 8 and 8.1, both versions can co-exist.

In this connection, there are a couple of methods to install Framework 3.5, where both of these oblige an internet connection.

METHOD 1

INSTALLING ON DEMAND – Once an application, compatible with Framework 3.5 is executed, it appears with a prompt window asking to install the said version.

Run the executable file of application compatible with 3.5 version of .Net Framework
The application will fail to start, requiring you to install this specific version
In the same message box, there would be an option stating Get .NET FRAMEWORK 3.5
On clicking this option, you will be redirected to its concerned webpage
You can now easily download and install it

METHOD 2

ENABLING THROUGH SYSTEM SETTINGS – It can also be manually enabled through the Control Panel. For this purpose,

Go to Control Panel, locate, and select to open Programs menu/category
In the left pane, additional settings can be viewed by click on Turn Windows Features on or off
In the appeared list, the option for .NET FRAMEWORK is to be checked and saved
This will also resultantly, connect to the server for downloading the required files.

By opting either of the above methods, the user might be stimulated with the stated Error Codes. This is due to failure in connecting to the servers for copying the prerequisite installation files. The reason might be a real problem in the Internet Connection or configuration of the user’s computer to use Windows Server Update Service (WSUS) in a replacement of Windows Update Service.

SOLUTION 1a

The first solution will probably work for most of the readers here. It’s related to a conflict between .Net Framework installer and few security updates from Microsoft. KB2966826, KB2966827 and KB2966828, the updates installed by Windows Update Service are cause of concern. To fix the issue, you just need to remove these updates and retry installing .Net Framework. Follow the instructions to uninstall the mentioned updates.

Goto Start Screen by pressing Windows key on the keyboard
Type ‘control panel’ and strike Enter key
At the Control Panel click Uninstall a program under Programs category
Click View installed updates from the left pane
Scroll and search for the updates named KB2966826 KB2966827 KB2966828
Once found select each and click Uninstall button

These updates can be later reinstalled once the problem is solved, either by running Windows Update yourself or leaving it to the system.

SOLUTION 1b

If the above solution dint work, the user is incited to ask the administrator for reconfiguring the system to use Windows Update instead of WSUS. To do so, a Windows 8(8.1) DVD needs to be inserted and specified guidelines need to be followed.

Insert a Windows 8 installation disc in CD/DVD Drive
Open Start Screen
Type ‘cmd’ to conduct a new Search
Locate Command Prompt, Right Click and choose ‘Run as Administrator’
In the black screen of Command Prompt, type
“Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs/LimitAccess”
Press Enter key

Note: D: in above stated command line indicates the drive containing installation media.

SOLUTION 2

As an alternative solution, you can predetermine a location of a shared folder or a WIM file, containing the requisite data for installation. This can be done by enabling a group policy setting and then providing a complete alternative path towards the installation data. To practice this method.

Press Windows key + W to conduct a new Search
Type ‘gpedit.msc’ in the Search box, and locate to open Edit Group Policy
In the left pane under Computer Configuration, expand Administrative Templates
Click to highlight System in the right pane
In right pane, locate Specify settings for optional component installation and component repair
Double click to open and then Enable the policy
In the same dialog box, under Alternative source file path, enter the correct network installation path (e.g. \\server\Win8InstlMedia\sources\sxs)
Click OK to save your changes and Exit Local Group Policy Editor

SOLUTION 3

You may not find Local Group Policy Editor in your copy of Windows, as it features only in certain versions of Windows. Another way to perform this function manually is described below.

Press Windows key + W to conduct a new Search
Type ‘regedit.exe’ in the Search box, and locate to open Registry Editor
In the left pane of Registry Editor, expand through HKEY_LOCAL_MACHINE to reach;
SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5
In the right panel, create DWORD Values and name them CBS, Install, and SP
Double click each entry to Modify and put 1 as their Value data
If the values already exist, make sure their Value data is set to 1
In the same area, create a String value and name it as InstallPath
Give the correct path in its Value data field (C:\Windows\Microsoft.NET\Framework\v3.5)
Click OK and Exit Registry Editor

Above declared techniques would have expectedly helped you in coping against error codes 0x800f0906 and 0x800f081f. It is again notified that you can keep both the versions at the same time.

The following are the steps to enable .NET Framework 3.5 (include .NET 2.0 and 3.0) feature in offline mode :

Step 1 :
Insert Windows 8 DVD or mount ISO image. The source of this feature can be found in folder E:\sources\sxs. (In this case E: the user’s drive letter on which the user has loaded Windows 8 Media.)
Step 2 :
Open CMD.EXE with Administrative Privileges.

Step 3 :
Run the following command Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:E:\sources\sxs /LimitAccess, and hit Enter.

After completing the installation of .NET Framework 3.5 you can see that the feature is enabled.

  Thank You! very much!!! I just totally depressed when my previous programs did not work on my windows 8.1 because of this crappy error, damn! microsoft should fix that in order to maintain its backward compatibility in certain programs since many applications now so far did not support .net framework 4-4.5. Thanks man! you saved my Day ^_^

  The Network Installation Path, is the path of windows setup on the Network your system is connected to.
  The path given in the post is just an example \\server\Windows Setup Folder\sources\sxs

  First confirm D: is your drive containing Windows 8/8.1 Install Disc
  
  Secondly Copy/Extract the folder sources\sxs to C: drive to a newly created directory (e.g DotNet35)
  Run the below command as Admin at Command Prompt
  
  Dism /online /enable-feature /featurename:NetFx3 /All /Source:C:\DotNet35\sources\sxs/LimitAccess

  Its the path from another PC/Device on the network, in-case you are on one.
