Attempting to download upgrades; Install button grayed out

[Joan Lankford]

I received an error message on screen saying I needed to
access a web site and download updates. My computer was
attacted with the blaster worm and I am having
difficulty, especially, with the D:/ drive. When I went
into the specified site, it will not allow me to download
the upgrades. The Install button is grayed out.

Any help would be greatly appreciated.

Respectfully,
J Lankford
