    I had the exact same problem, fought with it for several days, and finally got it fixed using a variation of the above procedures.

    If you download 3.5 and 3.5SP1, you may have noticed they have the same file names.
    I saved 3.5 as dotNetFx35setup.exe and renamed 3.5 SP1 doing a "Save As" dotNetFx35setupSP1.exe. DO NOT RUN THESE FIRST.

    I downloaded and ran the  Download .NET Framework Setup Cleanup Utility BEFORE I ran the 2 downloaded files above.
    Select ONLY 3.5 to remove when you run the cleanup tool.

    Even though 3.5 never installed correctly, the cleanup tool says it successfully cleaned 3.5

    Then I successfully installed dotNetFx35setup.exe.

    Then I successfully installed dotNetFx35setupSP1.exe.

    Run Windows Update and install the update for 3.5 SP1 and 3.5 Family Update (KB951847) x86

    Refresh your Check for Updates, then install Update to 3.5 SP1 for .Net Framework Assistant 1.0 x86 (KB963707)

    Refresh Check for Updates and install Windows Vista Service Pack 2 (KB948465)


    I don't know if everything I did was necessary, but it worked for me.

    Hope this works for you!
