I am on Windows Vista 64 bit on my computer. When I surf internet, with the help of Internet Explorer, and when I come across with Quicktime media I can see a message which says I need to download Quicktime player to watch the media file. But I already have it installed on my computer. I can see that in Add/Remove programs. In spite of that I click to download and install it on my computer but then nothing happens. I am still unable to see the Quicktime media file. So I am worried if Quicktime is actually compatible with Internet Explorer 64 bit? I don't want to use browser other than IE and so need some solution that works with this browser only. Can you tell me if Quicktime will not work on Internet Explorer 64-bit? If it will then how?
