LG L226WTQ monitor driver update

I updated my NVIDIA drivers for my SLI mode 8800GTX cards. That all worked
pretty well even thought I had to redownload from NVIDIA to get the control
panel to operate. However, now I'm getting prompted to update/install the
monitor driver from my LG L226WTQ LCD widescreen monitor. When I try to
update the driver, I get an error saying the update failed because access was
denied. I have tried this both as Administrator and my user account with
Administrator privileges. How do I enable this access ?

thanks
