Aside from the program folder residing in

C:\Program Files\The Layered Earth
(or C:\Program Files (x86)\The Layered Earth for 64-bit Windows installations)

the following folder also needs to be present on all networked systems:

Vista or Windows 7:
C:\ProgramData\Simulation Curriculum\The Layered Earth

Windows XP:
C:\Documents and Settings\All Users\Simulation Curriculum\The Layered Earth

If you wish to register the software once and have it pre-registered on network machines, then you may install it on one system, activate the license there and then copy the shared folder above across different systems.

In order to minimize program's need for map data from Internet (The Essential Layered Earth Data) you need to ensure that the additional 2 discs of data have been installed (their contents is installed in the shared directories above). Then you may disable network connection of The Layered Earth by going to File->Preferences->General and unchecking "Stream data from internet when available". You don't have to do this for every system as TLE properties are located in

Vista or Windows 7:
C:\Users\\AppData\Roaming\Simulation Curriculum\The Layered Earth

Windows XP:
C:\Documents and Settings\\Application Data\Simulation Curriculum\The Layered Earth

Therefore, once you set it up on one machine, you could propagate program preferences to accounts on all other systems.

There are different ways in which you could share The Essential Layered Earth Data (satellite imagery and topographic data) across different systems. One method is to copy

Vista or Windows 7:
C:\ProgramData\Simulation Curriculum\The Layered Earth\CacheData

Windows XP:
C:\Documents and Settings\All Users\Simulation Curriculum\The Layered Earth\CacheData

to a network drive and then go to File->Preferences->Advanced-> "Set Aux. Data Store" and set the new location of CacheData (this is equivalent to modifying tle.properties file by changing the remoteFileCache option).

There are more flexible method for doing this on a network setup.

You could have the entire C:\Documents and Settings\All Users\Simulation Curriculum\The Layered Earth folder live on a network by either using Microsoft's Folder redirection which is something similar to file/folder soft links on Linux (and would have to be supported by your Windows OS, mostly restricted to professional and server editions).

Another, more widely supported, method is to use simple Windows shortcuts. If you copy the entire C:\Documents and Settings\All Users\Simulation Curriculum\The Layered Earth (note that Windows XP default folder is referenced here, the equivalent for Vista/7 is at the beginning of this article) to a network drive and then create a shortcut to this mapped network drive folder in the same location and name it "The Layered Earth", The Layered Earth will simply use the network drive's location for files (including CacheData, Favorites and license file). This would be a simple method for sharing all of this essential files without having to modify TLE properties (you'll get automatic activation for all systems as well). Note that on startup, TLE will create The Layered Earth folder right beside the shortcut but this folder will contain no data as all data will come in through the shortcut itself.
