Trouble. My apologies for late reply. Thank you for your interest. Busy week end and when I do get on my computer, I just go round in ever decreasing circles and usually achieve nothing. The attachment that has been sent to me and received as Windows Live Mail is a Flight Simulation aircraft file .exe which I wish to include in my FS2004, Microsoft Games. My Windows 7, 64 bit has blocked access to this file on the grounds that it is potentially harmful. ANNPAT
