Thought that I'd pass this on as it may help some people. It's a less than
ideal solution, but it may be a work around until someone comes up with a
better solution.

I've been having problems running Flash (in particular http://www.afl.com.au/)
and have tried uninstalling and confirming all files are removed in
C:\Windows\System32\Macromed\Flash, as well as the registry updates that you
may have read in other postings here. None of these have worked for me...

I found right mouse clicking on the IE7 shortcut and choosing the "Run as
administrator" then going to the site in question all was fine... it works!!!

I'm not totally sure whether this is a Flash issue, though the web site
advises that it is. BTW my account does have administrative privileges.

Hope this may help...

Another alternative to the above...
Note: For the above solution you'll need to do this everytime you open up the
browser if you're planing on running flash. If you get sick of this you can
right mouse click on the IE icon and choose "properties" and "advance" and
check the "Run as administrator" checkbox. The issue then is Vista's UAC will
pop-up everytime you open IE. Again not a nice solution.

I hope Adobe fix this shortly.
