    Let me get started by giving my system settings:
    - Dell Optiplex GX620 w/Windows XP Pro SP3
    - Internet Explorer 7
    - Microsoft .NET Framework 2.0 Service Pack 2

    I just upgraded to Service Pack 3 and any time I try to install .NET 3.5, i
    receive a setup.exe error which reads "Microsoft .NET Framework 3.5 has
    encountered a problem during setup. Setup did not complete correctly." This
    happens every time. I tried installing the package from Windows Update and
    from a executable my work provided. Any ideas?

    Where to find .NET Framework 2.0 SP1, 2.0 SP2, 3.0 SP1, 3.0 SP2, 3.5 and
    3.5 SP1 setup log files

    Updated: what to do if other .NET Framework setup troubleshooting steps
    do not help

    There are several causes for .NET Framework runtime and SP installation
    failures. First, verify that .NET 2.0 SP2 is installed correctly.

  3. What Mow said, and/or...

    1. Before doing anything else, write down the .NET Framework versions which
    are already installed:

    How to determine which versions of the .NET Framework are installed and
    whether service packs have been applied

    2. Now see Resolution Method 2 in
    (ignore the title). After running the appropriate/needed tool, (re)install
    all .NET Framework versions manually using the download links on the page.
