I use Windows Live Mail 2011 (Build 15.4.3502.0922), in Windows 7 Pro 64. When I receive an email message that has an attachment, when I double click to open this attachment, nothing happens. Any kind of attachment, nothing happens. If I right click and choose "Open", nothing happens either. If I right click and choose Save As, I can save the file to disk and open it via Windows Explorer.
I would like to be able to double click to open the attachment. I tried to repair WLM but that didn't make any difference.
My antivirus is Microsoft Security Essentials.
Does anyone know anything about this issue?
