High there,
I ran the full install after I got an error in trying to upgrade an XP machine. I first used the Add/delete programs to remove the other versions of RB and then downloaded the new 3 beta and saved the file. I then ran the instal and it worked strait away. Just a tip - save to a different directory any thing you may be upset to loose. EG the Outlines, map, colors,Photo folders and after the instal is working copy them back into the correct folder.
