WinUpd Install Failure Code 643 (automatic) or 800700005 (manual)

I keep receiving this error code whenever I try to install Security Update
for Microsoft .NET Framework, Version 1.1 Service Pack 1 (KB886903) Which is
summarized as, "A security issue has been identified that could allow an
attacker to compromise your Windows-based system running the Microsoft .NET
Framework and gain access to restricted data. You can help protect your
computer by installing this update from Microsoft. After you install this
item, you may have to restart your computer. Details..."

How can I get past this? Please help!

Updates from the Windows Update Web site are not installed and an "Error 0x80070005:

This error message may occur if you have insufficient permissions to the Windows
Update registry keys. The WindowsUpdate.log file will also read errors 0x80070005 and
0x80080005.
