Preliminary Tasks: The following tasks must be run, prior to installing any Ultimate Terrain USA patch:

1. Start the "Ultimate Terrain Setup And Configuration" utility.  Then, make sure ALL Ultimate Terrain features are turned on.   This is necessary because deactivated Ultimate Terrain features are named different from what the patch expects.
2. Make sure FS2004 is not running !     It might be a good idea to reboot your PC before applying the patch, to ensure that there are no files locked by rogue FS2004 processes.   It has been reported that FS2004 will occasionally lock files, even though the application has been terminated.

Note:  Any of the patches can be rerun on top of themselves without getting things out of sync.   This means, that if you are unsure whether or not a patch took, you can always rerun it.   However, do not try and run an earlier patch on top of a later patch.
