As Flash 8 still not very popular - may be it's better to include Express Install feature into generated SWF file?
Please look at http://blog.deconcept.com/swfobject/ (section "Using Express Install with SWFObject") for necessary Action Script code

Pano2QTVR (flash projection) based on new conception - after v7 engine.
Important.
Flash8 - it's new innovation judgement - new age.
Flash9 and AS 3 - fine concept which began in version 8.
