This Fixit was not able to be completed/installed/whatever. I think this may be because I have XP with service pack 2 and you might need service pack 3. The Microsoft help page said that in order to install service pack 3 you have to have a 32 bit something, and there was something to click on to determine whether you had 32 or 64 bits. But when I clicked on it, a box came up with a whole lot of information, but I did not see where it said either 32 or 64. It seems odd that Windows wouldn't have installed service pack 3 if I needed it, since it must have done service pack 2 (I know I didn't install it).
You should do that a.s.a.p. as your machine is way out of date, has to be because support for XP SP2 and under stopped in July 2010, so your missing lots of security updates, no wonder there are issues.
