I have started getting a problem in my computer after I installing a Windows vista 64 bit on my computer. The problem is about the Email attachment. Yesterday I tried to release a attachment that came with a mail on my inbox. I couldn’t able to download and open it. First of all I thought that it has something to do with the Email client. So I decided to try in another computer. There it opened without any issue. Now I think that the issue has something to do with my computer and that is Windows Vista. Am I right? Is there any way to fix this issue without much effort and trouble?
