For a short while now, I have been having trouble bringing up a picture with Dell Picture Studio--Dell Image Expert.  Not that I ask it to bring it up with that software, but it is installed on the XPS 400 we got a year ago.  It wants me to insert a disc---and there are no discs with this computer other than the McAfee.  When I try to get out of that box, I get an error 1706 telling me that no valid source could be found for product Dell Picture Studio--Dell Image Ixpert.  The Windows Installer Could Not Continue.  At one point there is a box with a 1 in it.  Finally when I get out of all the boxes, the picture will come up at some point.  What is going on and how can it be fixed?  Like I said, there is no CD at all.
