Flash detection

hello

I have composed a CD with some flash movies. the first one is started by start.exe

fallowing internal movies are loades as .swf (=> the user needs the plugin, or NOT ???)

If the user has no internet connection, I would like to add a possibility to dected and install OFFLINE the macromedia flash player plugin from the CD ROM.

I just saw on tutorials the possibility to download the plugin ONLINE.

How can do all this OFFLINE ?

thanks for your help !
