I get to the part of the game where i am told to insert disc 2...i have disc 2 in the drive and i copied all the files to the scumm folder just like i did the for disc 1. but it will not work. Help?

I found the file but it says:
"The version of this file is not compatible with the version of windows you're running."

Help??

I have windows 7, and I really want to play The Curse of Monkey Island but when I go to install it, it tells me to go to the Install folder of the desk and run setup.exe and that file isnt there...what do i do?
