You should first check that you have the correct file for your operating system. You must have one of the following file:
ShopNCook.exe, SNCMenu.exe, SNCPro.exe or SNCReader.exe for Windows 98, ME, NT4, 2000, XP Service Pack 2, Vista or Windows 7
ShopNCook.zip, SNCMenu.zip, SNCPro.zip or SNCReader.zip for Mac OS X 10.2 or later
If you have trouble starting or finishing the installation, the file may be corrupted. You should try to download it again.
If you have trouble starting the software, you may have the Java virtual machine missing on your computer, or have an older version of Java. If the software cannot install automatically the latest version of Java, you should try to install and download it manually from http://www.java.com .
On Mac OS X:
The downloaded file with extension ".zip" (for example ShopNCook.zip) should expand automatically into a file with extension ".dmg" (for example ShopNCook.dmg). If it doesn't, you have to double-click on it. The file with .dmg extension should be mounted automatically as a new volume on your desktop. If it doesn't, you need to use the Disk Copy utility in your Application folder to mount it.
