I'm using XP Pro with "Automatic update" setup to inform me when there are
updates to install.
The updates are all "up to date" But I continually get a message that "you
have updates" for 1 that is "Security Update for Flash Player (KB923789).

I allow it to update but it says "unable to install Security Update for
Flash Player (KB923789)".
Troubleshooting todate:
I've repeated this process several times and restarted the computer.
I've removed Flash and reinstalled it.
I've updated Flash several times.
Windows will provide this information: Error Code 0x643
IE7 will not run Flash programs when visiting a website with Flash - and
this is the message screen the website provides:
"OOPS! You forgot to upload swfobject.js ! You must upload this file for
your form to work."

When using the Firefox browser, there is no problem.

Do I have a problem with IE7?
Why won't the Security Update install?
