Adobe error

[Crawdadr]

adobe reader could not open 'EQ2MAP-Updater-1.2.4-Setup[1].zip'
becuase it is either not a supported file type or because the file has been
damaged (for example, it was sent as an email attachment and wasn't
correctly decoded).

So far what I have tried:
I have unistalled adobe and reinstalled the latest version.
Updated my windows to service pack 2
Searched the adobe sight and did what it said but nothing worked.

I am using vista and frankly I am at my wits end. I loved eq2 maps and I want it back
