It means that your computer does not recognize the file type and therefor cannot auto assign a program to open it. Depending on what you download, the "open with" option will allow you to assign the appropriate program for the file.
Something to to with file types. I have the same problem on a clean install of XP sp2 on an amilo pro laptop
just download it again
you click where it says 'download'
It means that it can't open that type of file.
Download installation files from official adobe site. If it happens again then something missing on your computer and I cant help you.
Download VLC player!!
either or, there is no difference other that one saves it, and the other (open) saves it first, then opens it.

Download the maplestory installer first. That is what the .msi is.
