I Love Spelling Install Problems

Question

I have tried to load DK Multimedia's "I love spelling" CD ROM on 3 different PC's ( 2 XP & one Vista) on the auto install process each time the programme fails to launch saying "The sound software has not been properly installed or is disabled" - it then forces me to quit the programme.

How do I source and load up the necessary drivers? I am guessing that this is the problem - your advice on this approach or any other you can suggest would be most appreciated.
