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
If this is a Windows Live Mail (HotMail) account, you will likely need to have the person sending you the file compress (zip) it or otherwise alter the file extension to something other than .exe (.jpg and change it back to .exe when you save it) before sending. It is not Windows 7 blocking the file.
Trouble is on the money. But I would also suggest it is rather pondrous to send such large files by Email attachments. You could ask your correspondent to put it up on a hosting site? Several are free.
Here is a nice one that I use, for example.
