Code 800F0816 when installing Service pack 1 in Windows Vista

I had an 0146 error code, I replaced the hard drive and installed Vista from a DVD of resettlement. So far, all of the updates has loaded fine. When it comes time to download and install service pack 1, it ok until the end it says that is is unable to load the update and I get and error message stating the Code 800F0816. What should I try to get this pack to load?

I went on the link. What happens is the Welcome to Windows screen. A little lower I can 'get it now' [Microsoft] Security Essentials...

Microsoft Security Essentials is available only when the WGA scan does not detect the presence of a valid, fully functional antivirus application.  Yet another symptom of an existing infection (ongoing).

Your 'copy' of the VAS is installed illegally & will NOT work correctly.

Do a clean install. After completing the clean install this time (in order):

1. uninstall the Trend Micro application (which will also be reinstalled, but now invalid) & restart.

2 download/install Microsoft Security Essentials (free), instead of customer Service: http://www.microsoft.com/security_essentials/default.aspx

3. launch repeated manual checks for Windows Updates & install updates they are offered (follow all prompts) until you finally got SP2 & all post-SP2 installed updates.

Do NOTHING else online (e.g., navigation electronic control cat; download/installation of other stuff) until you have completed step 3 above.

Also do NOT connect the computer to local networks (i.e. other computers) or restore all backed up data.

If you need additional assistance with the clean install, please start a new thread in this forum: http://answers.microsoft.com/en-us/windows/forum/windows_vista-system

Notes:

=> You will not be able go to Win7 unless & until Vista SP1 is installed.

-Online a manufacturer OEM version of Windows is permanently tied to the computer on which it is preinstalled. You may not use the OEM Win7 disc to upgrade Vista to Win7 computer or do a clean install of Win7.

Good luck! More & outta here...
