help! : Screensaver scr to exe file?

[~Pheonixx~]

i dont know if anyone can help as this is not actually a xara 3d problem but it is related.
i am new to this and having experimented have got to grips with the program somewhat. I have created a screensaver in x3d and have saved it and it works well on my computer, however i would like to be able to pack it as a self extracting exe file for others to use, i cannot find out how to do this.
has anyone got any ideas?
thanx.
