Flash player detection problems

1

I’ve created a whole website for a customer on flash however i have forgotten to include putting in the flash player detection code. I actually have no clue how to do it, i’ve searched and found the flash player detection kit here http://www.adobe.com/products/flashplayer/download/detection_kit/ and i downloaded it but where do i put it. what file do i use, do i add code to the html that embeds the .swf on the page or do i add the code directly in the .swf file, and where. I also am having troubles with my preloader it seems that there is a white box before the actual preloader pops up and then the website displays, how to i get rid of the white box. sorry if this sounds confusing but i need help because the website is already on the internet, the url is legaldepartment.ca and i’d like to get these problems fixed so her clients don’t encounter them. thanks for your time.
