hello, I have just upgraded to Ultimate, and am looking at M/soft's various optional add-ons, but (while I can just about work out that I probably have the 86 version since I don't have the 64-bit version - is that a kind way to treat ungeeks ?) I don't know whether I have the N version, the un-N version or what (I get the impression the KN version is for businesses - yes ?). All my pc seems able to tell me is that I have version 6.1, number 7600. (When i try to find Windows7 on the computer, nothing useful transpires, mostly bits of images, making one wonder if it's really there) I am also unclear whether I need Windows Media Player, if I have it, or what, since one attempt at downloading said I couldn't install it for Firefox - but offered me manual install, which aborted.... Sorry to be such a klutz, adj
