If you follow this link it takes you back to the page where it tells you about the gdi file which I have already put into the \winnt\system32 folder.
A second and very annoying problem is on one of the other machines in the add/remove programs option, all you can see is the little icon and no text on the right so there is basically a big white box with tiny icons all the way down the left side. I have no idea how to fix this problem so hopefully somebody here can advise me!
Any info about either of these problems would be appreciated.
