The only version you really should be using to publish to a web page is FlashVR or HTML5 for Safari Browser
Using FlashVR(SWF) will work but the loading screen will not function correctly. Unless you use a work around offered by forum member MADMUX. The single SWF file is really for Flash developers who wish to incorporate into their Flash AS3 projects. Or for those who wish to pass on a single Flash file to be viewed "locally".
