Symptoms

When you try to install the Microsoft .NET Framework 3.5 on a computer that is running Windows 8 or Windows Server 2012, you receive one of the following error codes:

0x800F0906

0x800F081F

0x800F0907

Notes

• This problem may occur when you use an installation wizard, the Deployment Image Servicing and Management (DISM) tool, or Windows PowerShell commands to enable the .NET Framework 3.5. 
• For the complete list of the error messages that are associated with these error codes, go to the "More information" section.

Cause

In Windows 8 and in Windows Server 2012, the .Net Framework 3.5 is a Feature on Demand. The metadata for Features on Demand are included in Windows 8 and in Windows Server 2012. However, the binaries and other files associated with the feature are not included. When you enable the feature, Windows tries to contact Windows Update to download the missing information to install the feature.

The network configuration and how computers are configured to install updates in the environment can affect this process. Therefore, you may encounter errors when you first install such features.

Resolution

To resolve this problem, use one of the following methods, as appropriate for the error code that you are receiving.

Error code: 0x800F0906

This error code occurs because the computer cannot download the required files from Windows Update.

This behavior can be caused by network, proxy, or firewall configurations or by network, proxy, or firewall failures. To resolve this problem, try to connect to the following Microsoft website:

Microsoft Update

If you cannot access this website, check your Internet connection or contact the network administrator to determine whether there is a configuration that blocks access to the website.

This behavior can also be caused by a system administrator who configures the computer to use Windows Server Update Services (WSUS) instead of the Microsoft Windows Update server for servicing. In this case, contact your system administrator and request that they enable the Specify settings for optional component installation and component repair Group Policy setting and configure the Alternate source file path value or select the Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS) option.

To configure the Group Policy setting, follow these steps:

1. Start the Local Group Policy Editor or Group Policy Management Console.
   
   
2. Expand Computer Configuration, expand Administrative Templates, and then select System.
   
   
3. Open the Specify settings for optional component installation and component repair Group Policy setting, and then select Enabled.
   
   
4. If you want to specify an alternative source file, in the Alternate source file path box, specify a fully qualified path of a shared folder that contains the contents of the \sources\sxs folder from the installation media. Or, specify a WIM file. To specify a WIM file as an alternative source file location, add the prefix WIM: to the path, and then add the index of the image that you want to use in the WIM file as a suffix. The following are examples of values that you can specify:
   1. Path of a shared folder: \\server_name\share\Win8sxs
   2. Path of a WIM file, in which 3 represents the index of the image in which the feature files are found: WIM: \\server_name\share\install.wim:3
5. If it is applicable to do this, select the Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS) check box.
6. Tap or click OK.
7. At an elevated command prompt, type the following command and then press Enter to apply the policy immediately:
   gpupdate /force

Or, you can use the Windows installation media as the file source when you enable the .NET Framework 3.5 feature. To do this, follow these steps:

1. Insert the Windows 8 or Windows Server 2012 installation media.
2. At an elevated command prompt, run the following command:
   Dism /online /enable-feature /featurename:NetFx3 /All /Source::\sources\sxs /LimitAccess
   Note In this command, is a placeholder for the drive letter for the DVD drive or for the Windows 8 installation media. For example, you run the following command:
   Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess

Steps for Windows Server 2012

Error code: 0x800F081F

This error code can occur when an alternative installation source is specified and one of the following conditions is true:

• The location that is specified by the path does not contain the files that are required to install the feature.
• The user who tries to install the feature does not have at least READ access to the location and to the files.
• The set of installation files is corrupted, incomplete, or invalid for the version of Windows that you are running.

To resolve this problem, make sure that the full path of the source is correct (x:\sources\sxs) and that you have at least Read access to the location. To do this, try to access the source directly from the affected computer. Verify that the installation source contains a valid and complete set of files. If the problem persists, try to use a different installation source.

Error code: 0x800F0907

This error code occurs if an alternative installation source is not specified or is invalid and if the Specify settings for optional component installation and component repair Group Policy setting is configured to "Never attempt to download payload from Windows Update."

To resolve this problem, review the policy setting to determine whether it is appropriate for your environment. If you do not want to download feature payloads from Windows Update, consider configuring the "Alternate source file path" value in the Group policy setting.

Note You must be a member of the Administrators group to change Group Policy settings on the local computer. If the Group Policy settings for the computer that you want to manage are controlled at the domain level, contact your system administrator.

To do this, follow these steps:

1. Start Local Group Policy Editor or Group Policy Management Console as applicable in your environment.
2. Expand Computer Configuration, expand Administrative Templates, and then select System.
3. Open the Specify settings for optional component installation and component repair Group Policy setting, and then select Enabled.
4. Determine whether the Never attempt to download payload from Windows Update Group Policy setting is enabled, and then determine the desired setting for your environment.
5. If you want to specify an alternate source file, in the Alternate source file path box, specify a fully qualified path of a shared folder that contains the contents of the \sources\sxs folder from the installation media. Or, specify a WIM file. To specify a WIM file as an alternative source file location, add the prefix WIM: to the path, and then add the index of the image that you want to use in the WIM file as a suffix. The following are examples of values that you can specify:
   • Path of a shared folder: \\server_name\share\Win8sxs
   • Path of a WIM file, in which 3 represents the index of the image in which the feature files are found: WIM: \\server_name\share\install.wim:3
6. If you want, select the Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS) check box.
7. Tap or click OK.
8. At an elevated command prompt, type the following command and then press Enter to apply the policy immediately:
   gpupdate /force
