    The download may have got corrupt, or you downloaded a version not for Windows. Try again from the SAFE Portal 

    If it still doesn't work, try from another browser.

    If you're running XP you could also try right-click the file and select Properties and click Unblock if there's such a button.

    If nothing works, what is the file size of the downloaded file?

    What browser do you have and did you try from another browser? What Windows version?


    Test another download as a reference, right click this link and save the file. Then check its file size:
