I beleive that I sign in as adminstrator every time. I do not know how to change how I sign in. A freind installed windows 2000 pro for me and that is how he set it up. It probably is to late to make any difference now. I do not know enough to do much checking out the system. Some of the other programs I can't execute are Partition Magic,Photoshop, EZ Creator 5 and also I downloaded a Sony camera driver that will not execute.:9
