Many thanks for the quick reply, but I'm afraid it doesn't quite answer my question (unless I've missed something on the website.
My apologies. I should have been more clear.
She has apparently installed the flash player from that link, but she still cannot open the swf file I sent her, because windows doesn't know which application to open it with.
Can I associate the .swf extention with the player manually, just like any other application, and if so, where do I locate the flash player executable?
