Programs on CD

[Shari]

With my nifty new CD burner I can now put software on CD, not just 
online downloads.  Which leads to a problemo...

As CD's cannot write to themselves, and all of my programs write to 
themselves, saving user info in fields etc., I am assuming the only 
way to put a program on CD is to have it write all data to an 
external file on the user's hard disk.  So if a user is playing a 
game with high scores, the high score data is stored in a file on the 
HD, even if the program itself is on a CD.

But assuming anything is always a bad idea, so I'd like to know how 
others are handling this, if differently.

Perhaps the CD would just have an installer to install the program 
onto their hard drive?  Hmm....

Thoughts, anyone?
