  • Hi hatem nimer,

    Welcome to MSDN forum.

    >>windows tell me that net framwork is installed before

    To check if .net framework 3.5 is installed on your pc, you could view the registry:

    1. On the Start menu, choose Run.
    2. In the Open box, enter regedit.exe.

           You must have administrative credentials to run regedit.exe.

    1. In the Registry Editor, open the      following subkey:


    The installed versions are listed under the NDP subkey. The version number is stored in the Version entry, please refer to this.

    If you could find .net framework 3.5, try to use the .NET Framework setup verification tool:

    to verify and once it found any corrupted, you can use the .NET Framework Repair Tool: to repair it.

    Meanwhile, you can have a try with other ways to install the .NET Framework 3.5.

    1.If an app requires the .NET Framework 3.5, but doesn't find that version enabled on your computer, it displays the following message box, either during installation, or when you run the app for the first time. In the message box, choose Install this feature to enable the .NET Framework 3.5. This option requires an Internet connection.

    2. Enable the .NET Framework 3.5 in Control Panel

    • Press the Windows key on your keyboard, type Windows Features, and press Enter. This brings up the Turn Windows features on or off dialog box.
    • Select the .NET Framework 3.5 (includes .NET 2.0 and 3.0) check box, press OK, and reboot your computer if prompted.

    You could also use the command sfc /scannow to see if you have any corrupted system files.

    if this issue still persists, I need your help to collect installation log. Please use to gather the installation logs. After using it, you will find under %temp% folder. Please upload the file to and share the link here.

  • The heading of your problem says that you are not able to update Windows.

    Windows update error is usually caused by time/date issue, file corruption or registry problem and it's not difficult to fix it. The error happens when system update fails and the failure brings about data mismatch problem. Thus deletion of these corrupted files helps eliminate the error.

    .NET framework 3.5 may be present in your system and you may have not enabled it. Follow these steps to enable it:
    1. Press the Windows key Screenshot of the Windows key logo. on your keyboard, type "Windows Features", and press Enter.
    2. The Turn Windows features on or off dialog box appears.
    3. Select the .NET Framework 3.5 (includes .NET 2.0 and 3.0) check box, select OK, and reboot your computer if prompted.
