If SP3 was downloaded with an anti-virus, or anti-spyware, program
running, you may have a bad installation.

* If the configuration of your antivirus software prevents certain system
files from being changed, SP3 installation might fail. Try temporarily
disabling your antivirus software. You can usually do this by
right-clicking your antivirus program icon (which typically appears in the
bottom right-hand corner of the computer screen) and clicking Disable.
* If you disable your antivirus software before you install the service
pack, be sure that you are aware of the risks involved, and be sure to
enable it after the service pack is installed.
Remove SP3 via Add/Remove Programs, reboot and download and install it
again. Before you do, turn off your anti-virus and any anti-spyware
programs such as Windows Defender. If you use a third party firewall,
disable it and turn on the Windows Firewall in the Control Panel for the
installation. Once SP3 is in and working, you can enable the third party
firewall and turn of the Windows Firewall. Do not keep both running.
