I have always thought I had Windows Vista 32 Home Premium but this morning I was looking at the printed copy of my Belarc Advisor report and it says I have:

Windows Vista Home Premium (build 6000)
2.30 gigahertz AMD Athlon 64 X2 Dual Core.
Does this mean I have 64 instead of the 32 as I thought? What got me interested in this is because I found a web site that lists XP games that are compatible with Vista and it depends on which you have--either 32 or 64 for which games to work. My granddaughter is coming to visit me this evening for the weekend and I have a Reader Rabbit game for her but its requirements are for Windows XP. I am trying to find out if this game will work on my computer or not so that she will have something to play while she is here.
Thanks,
