Okay, I think I get that. However, I'm not sure what XP64 is (I have Windows\nXP) and I don't have Vista. What I don't understand is that Microsoft\nupdates is supposedly looking at "your" system and telling you what updates\nare needed for your system. If that is true, then why would they indicate\nthat I needed this update if I don't have Vista??\n\nI am not a computer geek and I don't understand half of what I read in these\nposts, etc. I get an icon that tells me that I have "critical" updates to\nensure the security of my system and I try to do what I'm told. When it\ndoesn't work, it freaks me out and I just want to understand whether I'm\nsupposed to install everything the updates tell me to. If I'm supposed to\nhave them, I just need to know how to fix this problem.
