Thanks Guys for the replies. My Version does appear to be right. I have to thank NTFS members, for pointing me in the right direction to find a download site that had a Resume option, and for all the other bits of advice I needed before downloading.
Like I said it took me 10 hours to download and I lost connections several times during that time, so I needed to be near the computer all the time. I have now copied it to disc, and installed it on two other computers for friends. It appears to have loaded OK, but I got the following error message, which after I cancelled it, hasn't returned.
%Remove_Nodir_Error%
I tried serching Microsoft but didn't find any link.
