How do I run the Earth Trails: Mississippi River Software Update?
You must have the previous version (1.2) of Earth Trails: Mississippi River already installed on your computer. This update will not install the program on its own; it fixes the code you already have.

Download the appropriate Windows or Macintosh update. Double click the update icon to run the new version. By default, the program installs in the Mississippi River folder on the hard drive. You may choose another location to save the updated program.

Please Note
The upgrade DOES NOT save to or change the CD-ROM. You need to download this upgrade to every computer you plan to use Earth Trails: Mississippi River on. You will still need the CD-ROM to use the program.
