Need to Create Screen Saver from Scratch

Need to Create Screen Saver from Scratch

I've hit a bit of a stump on the road to my goal of creating a screen
saver. Before I began this project I did research and everyone urged me to
create the screen saver using flash.. in which I did. Now I face the issue
of converting it to an SCR (screen saver format for windows) . Now I've
done my research and downloaded Instantstorm only to be disappointed by
it's lack of 64-bit support and/or Multi-monitor support (Scaled mirroring
across screens if resolution of main screen is different from other
screens).
Can anyone tell me what is the proper way of creating an animated screen
saver from scratch (or from the flash file I created preferably) which is
fully compatible with 64-bit and has the ability to display the screen
saver on multiple monitors.
