Cannot Install .NET 3.51 RRS feed

  • General discussion

  • Hello...!!!

    I'm unable to install .NET Framework 3.5 (Install_file: "dotnetfx35.exe").

    At first I upgraded Windows Installer (from 4.0.6001.0 to 4.5.6001.22162) and rebooted.

    But I got the same message in the error register:

    [05/16/09,12:42:17] Microsoft .NET Framework 3.0SP1 (CBS): [2] Error: Installation failed for component Microsoft .NET Framework 3.0SP1 (CBS). MSI returned error code -2146762496
    [05/16/09,12:42:48] WapUI: [2] DepCheck indicates Microsoft .NET Framework 3.0SP1 (CBS) is not installed.

    This is the file:

    I'm using Windows Vista Home Premium SP1

    Thanks in advance for any help provided...!!!
