Apple Application Support download for Windows XP

[John Mancini]

Hello, I am trying to download Apple Application Support on my Dell so I can read or play attachment sent to me. When I click to open the attachment a window drops and says "Download Application
Support". What do I have to do to read my email attachment?

What is the attachment? If it's a movie file, install Quicktime.
