  • Hi,

     

    In .NET Framework 3.5 SP1, the .NET Framework Assistant enables Firefox to use the ClickOnce technology that is included in the .NET Framework. The .NET Framework Assistant is added at the machine-level to enable its functionality for all users on the machine. As a result, the Uninstall button is shown as unavailable in the Firefox Add-ons list because standard users are not permitted to uninstall machine-level components. In this update for .NET Framework 3.5 SP1 and in Windows 7, the .NET Framework Assistant will be installed on a per-user basis. As a result, the Uninstall button will be functional in the Firefox Add-ons list. This update will also make this version of the .NET Framework Assistant for Firefox compatible with future versions of the Firefox browser. To properly update the .NET Framework Assistant, this update must be applied while the extension is enabled in Firefox. To remedy the result of installing this update while the extension was disabled, uninstall the update, re-enable the extension, and reinstall the update. Updates to the .NET Framework Assistant may include updates to the Windows Presentation Foundation Plug-in for Firefox causing it to be enabled upon its initial update.

     

    As you do not use Firefox, you do not need to install this update and I am afraid that this update cannot installed on your system if you do not have Firefox installed.

     

    This could be a incorrect update offering. I suggest you simply hide this update and it will not be offered to you again.

  • Hi,

     

    Do you use Firefox?

     

    KB963707 is an update to .NET Framework 3.5 SP1 for the .NET Framework Assistant 1.0 for Firefox.

     

    I understand that it may be inconvenient for you to reinstall .NET Framework. However, usually the cause of the issue that we cannot install .Net Framework related updates is certain .Net Framework components are corrupted. We have to uninstall all .NET Framework components and then reinstall them.

     

    Here are the detailed steps:

     

    Step 1.Completely remove .NET Framework

    ====================

    1. Please download dotnetfx_cleanup_tool.zip from the following site and extract it.

     

    http://blogs.msdn.com/astebner/attachment/8904493.ashx

     

    2. Double click cleanup_tool.exe to run the tool.

    3. Please follow the instruction and click Cleanup now to remove .NET Framework - All versions.

     

    Then, please continue to the next steps.

     

    Step 2.Remove related files in Safe Mode

    ====================

    1. Restart the computer and keep pressing the F8 key until the Windows Startup menu appears.

    2. Choose Safe Mode, and press Enter.

    3. Click "Start" -> "Run", type "%windir%" (without quotation marks) and press "OK".

    4. Locate "assembly" folder and right click on it and choose Rename to rename it to assemblyold.

    5. Click "Start" -> "Run", type "%temp%" (without quotation marks) and press "OK".

    6. Delete all the files in the open folder.

    7. Click "Start" -> "Run", type "%windir%\Microsoft.NET" (without quotation marks) and press "OK". 

    8. Right click on the folder Framework and choose Rename to rename it to Frameworkold.

    9. Restart the system to Normal Mode.

     

    After restarting, please try to install .Net Framework 3.5 again.

     

    Step 3.Manually downloading and installing Microsoft .NET Framework 3.5

    ===========================

    1. Click the following link:

     

    Microsoft .NET Framework 3.5

    http://download.microsoft.com/download/7/0/3/703455ee-a747-4cc8-bd3e-98a615c3aedb/dotNetFx35setup.exe

     

    Microsoft .NET Framework 3.5 Service Pack 1.

    http://download.microsoft.com/download/2/0/e/20e90413-712f-438c-988e-fdaa79a8ac3d/dotnetfx35.exe

     

    2. When the file download window appears, please click "Save", and follow the directions to save it on the Desktop. After downloading the Microsoft .NET Framework 3.5 and SP1 setup file on your Desktop, double-click to manually install them.

    Hi Tim,

    No, the box doesn't have Firefox install. Do you have another approach?
    Why WU prompts for Firefox update since there's no Firefox installed?
