Win 7 Update KB2687499 and Error 80070663

My HP Pavilion dv7 runs Windows 7 and Office Small Business 2007. Since Update KB2687499 was released it has failed to install repeatedly. Other updates since have installed without a problem.

I went through the list of Windows Update help options such as disabled Windows Firewall, Disabled my Anti-Virus (Norton Internet Security) and ran several FixIt options that pertained to that error code. Nothing worked. I have also tried to install the

KB with the Office 2007 CD installed which didn't change anything.

After that I searched this forum and have tried everything I can find in other posts related to this KB or Error message.

This includes directly downloading the file (msxml52007-kb2687499-fullfile-x86-glb.exe) but it gets an error message that says, "An Error Occured while Running Detection." I have also tried to run the file as an Administrator, while in a Clean Boot and

even in Safe Mode (with networking)- but it always produces the same error.

I have ran Office Diagnostics twice- once without and once with the Office 2007 CD installed. It didn't find a problem either time, nor have other system scans for viruses, errors, checkdisk problems, etc.

Following the advice from a post on this forum I have used msconfig.exe to perform a clean boot and it still failed to install- both from Windows Update as well as from running the file directly.

The last thing I tried was to delete Office and reinstall it. Office failed to delete. When I rebooted all the software was still on the machine (and launched) however Windows Update wanted to reload KB963671, SP3 and 7 other updates. After a reboot Windows

Updates came back to KB2687499 which continues to fail.

Other things to note:

In Control Panel-&gtPrograms and Features, when I right click on Microsoft Office Small Business 2007 and select "Change" a window opens that says, "Please wait while setup prepares the necessary files," but within a few seconds the window disappears. After

that nothing happens. It does not open setup or allow me to do anything at all. It does this in a clean boot as well.

When I install my Office 2007 CD the Setup fails to launch (even in a clean boot). The CD does not appear to be damaged or dirty. I can right click on it and browse the files without a problem.

What's my next option... other than to just hide the update?

Thanks

Sid
