At South Davis Junior High we purchased 35 licenses for KerbalEdu to use with a ninth grade Physics class. We decided to install the software in the school library computer lab. Davis School District has a District-wide Microsoft network and every student and teacher in our District has an account with a unique login ID. They cannot use any computer without first logging in to the network. Each user on the network has 1 gigabyte of "home" network storage space on a drive mapped as "H:" (this is in addition to Microsoft OneDrive). Students are taught to save all of their work to OneDrive (which can be accessed at home) or to H: (which cannot). The advantage of the H: drive for software setup is that "H:" always points to the home directory of whomever is logged in at the time. In our student computer labs we use the program "DeepFreeze" to prevent students from installing software, changing the settings, or bringing in malware. Each time a "frozen" computer is rebooted, it comes back up looking and working like we intend it to. This means that any work saved to C: (including a KerbalEdu session) will disappear every time the computer is restarted. We were very pleased to learn of the edusettings.cfg file for KerbalEdu. This allows us to set up the student computers to automatically redirect KerbalEdu saves to the personal home directory of the user where they will not disappear upon shutdown and where they are accessible no matter which school computer a student logs in to. Nevertheless, it took some trial and error to get the config file to work properly. I learned that it is more accurate to think of the location specified in your edusettings.cfg file as a place to download from than a place to upload to. The first mistake I made was to set the config file to "externalSavesDirectory = H:" When I tried to run KerbalEdu, it soon froze up completely. It turns out that Kerbal was trying to download every file in my network home directory to C:\KerbalEdu\saves. Lesson one, then, was that you need to have a separate, empty, folder in your home directory for Kerbal to save to. This led to my next problem, though. I changed my config file to say "externalSavesDirectory = H:/KerbalSaves," but I mistakenly thought that every user would need to manually create a "KerbalSaves" folder on H: before they ran the game. This is not true. When a person runs the program for the first time, it creates the folder for them and uploads the contents of the C:/<program directory>/KerbalEdu/saves folder. However, mistakenly creating a "KerbalSaves" folder manually eventually taught me more about the program. Despite having one's saved files in a network home directory, Kerbal does NOT use them there. When the program is running, it wants to have your files in the "saves" folder in the program installation directory (in our case, C:\KerbalEdu\saves). What the config file does is copy the contents of the specified network folder into the C:\<local directory>\ KerbalEdu\saves folder every time you run the program. At the same time, it deletes anything else (like a prior student's game) from the local Ã¢â‚¬Å“savesÃ¢â‚¬Â folder. Another thing I learned is that the install of Kerbal Edu puts two folders into the local "saves" folder. These are "training" and "scenarios." The problem I created for myself was that by creating an empty "KerbalSaves" folder, I was inadvertently deleting the training and scenarios folders on C:. Kerbal was replacing them with the empty contents of my H:\KerbalSaves" folder when I launched the program!! I learned this when training and scenarios would not run from the game menu. This also meant, when I "refroze" the computer, that NO ONE got the training and scenario folders. I also made the mistake of "freezing" a computer with an active game session saved on it. This resulted in every new user on that computer getting a copy of that game file uploaded into their H:\Kerbal Saves folder. Summary. It is important that the person who installs the program for the first time have no folder that matches the name of the folder that the edusettings.cfg file points to. After the game is installed, do not run the game until you have put your config file into the program directory. When you run the game (and enter the license number) your personal network "<savegame>" directory will be created (containing the training and scenarios folders). This is OK, but if you are installing to more than one computer, DO NOT have any other game files in your network <savegame> folder when installing. It is OK if "training" and "scenarios" are there because they will only be overwriting themselves (on C:) when the newly installed game on each computer runs.
