The Problem:
---------------------------
I have a website which allows visitors to download a software program.
I have designed the site so that the download link is contained in a
Flash movie. The link points to a Javascript function contained in the
same webpage which contains the Flash movie.

Flash Code :
 on(release){ getURL("javascript:download()"); }
 
Javascript Function:
 function download(){ 
  window.document.getElementById("frameB").src='http://www.mystore.com/Anything.exe';
 }
 
 
The problem my users are experiencing is that if they use IE6 and
click on the Flash movie ,  a security panel opens up in the top bar
of IE. Clicking on the bar and selecting "Allow blocked content" lets
a user download the Anything.exe from mystore.com
 
This doesnot happen in Firefox or any other browser. Nor does this
happen when the javascript function is called from a text/graphic
link. The security issue is scaring my customers away!
 

Objective:
----------
I just need a flash button that triggers an .exe file download without
producing the security warning mentioned above.

you need a valid security certificate if you wan to get rid of that
security message.

The EXE being downloaded is already signed so I presume you are
referring to an SSL Certificate. If so, wouldn't that mean the site
has to be in HTTPS ?

Yes, the site will need a valid SSL certificate.
