This sections contains instructions for system administrators, in addition to the section Installation and configuration.

Installation and configuration

1. What operating systems are supported?
   EDT is a MS-Windows program that can be installed on computers running the 32-bits edition of Windows XP, Windows Vista or Windows 7. The 64-bits editions of these operating systems are not supported and cannot run the EDT software without taking the steps described below.
2. My operating system is not supported. Can I still run EDT?
   Only if you run the 32-bits edition of Windows XP, Windows Vista or Windows 7 inside a virtual machine. You can use software like Virtual Box (free, runs on Windows, Linux and OS-X) , VMware Workstation or Virtual PC to do this. If you run the 64-bits version of Windows 7 Professional, Enterprise or Ultimate, you can install EDT in XP Mode
3. EDT doesn't start. Why doesn't EDT start when I click on an EDT simulation in my browser?
   To start an EDT simulation from the browser, the EDT software (version 4.0 or later) has to be installed first. You can download the latest version of the software here.
   When the EDT software is installed and nothing happens when you click on a simulation, you need to enable downloads in your browser.
   When the EDT software is installed and the file is downloaded, but the EDT software does not start, you should choose to open the file directly. When you are asked to select an application, select EDT (by default installed to C:\Program Files\edt\bin\simulator.exe).
   To always open the file in Google Chrome, click the arrow next to the file button in the downloads bar and select 'Always open files of this type'
4. Why do I get the message "Dongle not found"?
   You are using an old version of the EDT software. Upgrade to EDT version 4.0 or later. You can download the latest version of the software here
5. Why do I get the message: "Invalid failure file. The simulator requires a failure file version X.X or higher"?
   Make sure the latest version of EDT is installed and the system clock of your computer is set to the current date
6. Why do I get the message in Windows XP: "Initialization failed. Not enough memory or the file is damaged."?
   This message occurs when you have no permission to write to the Windows Temp folder. For more information see the next question
7. Why can I only start EDT in Windows XP as an administrator?
   When you want to use EDT as a normal user (without permission to administer the computer) in Windows XP, you have to give the user permission to read from and write to the folder C:\Windows\Temp. Change the permissions of this folder. For more information, see the Microsoft support site.
   If is it not desirable or possible to grant these permissions, you can also change the TEMP variable in this registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment from:
   

   %SystemRoot%\TEMP

   to:

   %UserProfile%\Local Settings\Temp

8. Can I use EDT from behind a proxy-server?
   When you have no direct access to the internet, you can use a proxy server. EDT uses cURL to exchange data with the Electude webserver. You can configure cURL to use a HTTP proxy server. Edit the configuration file C:\Program Files\edt\bin\curl\_curlrc using a text editor (e.g. Notepad). Add this line:

   proxy = <em>proxyserver</em>:<em>port</em>

   where proxyserver is the name or the ip-address of the proxy server and port is the number of the port the proxy uses. For more options, like proxy authentication, see the comments in the configuration file and the comprehensive documentation in C:\Program Files\edt\bin\curl
9. What does the message mean that DPI setting of the screen is incorrect?
   When the screen is set to an incorrect number of dots per inch, the windows of EDT will not be displayed correctly. EDT only runs correctly on the standard setting of 96 DPI. For more information see the Microsoft site

Using the software

1. Why can I only run EDT in demo mode?
   To use all functions in EDT, an account in the Argo LMS is required. Contact the teacher at your school, your training institute
2. How do I start the software?
   In Argo 4.0 or higher, EDT is started by logging on to the Argo site of your organistation (school or company) and clicking on an EDT simulation.
   In older versions of the Argo E-learning environment, EDT is started by selecting EDT->Simulator from the Windows Start menu and log in
3. Where do I find the documention necessary to trouble shoot the vehicle that is simulated?
   In the EDT software, select by clicking the question mark in the right hand toolbar, the option 'Documentation'. It contains this information:
   • the electric circuit diagram with pin numbers and wire colours;
   • the location of all components;
   • the relevant electrical specifications of the components;
   • a list of possible fault codes
4. How do I use the tools? How do I navigate to a component?
   In the EDT software, select by clicking the question mark in the right hand toolbar, the option 'Program operation'. Here all tools and menu-options are explained. Navigation in the engine compartment is explained as well

System administration

1. What settings are changed in the registry during installation?
   The installation proces creates the registry file C:\Program Files\edt\edt.reg. This file contains all changes that were made to the registry during installation. These changes are requires to associate EDT files with the software.
   The only value that depends on the location that was chosen during installation is HKEY_CLASSES_ROOT\EDT file\shell\open\command
2. Can I copy the EDT software to a network server?
   Yes. It is however required that the drive or folder of the server is mapped as a network drive. You cannot use the software via a UNC path.
   Select a network location during installation. After installation, make sure all files in subfolder bin are marked as 'Read only', otherwise users will not be able to run the software concurrently.
   See the next question for a step-by-step instruction
3. How do I install the EDT software easily in a network?
   Follow these instructions to install the software on a central server, that is mapped as a network drive on all clients that need to run the software.
   1. Install the software from one of the clients on the network drive
   2. Test the software. If necessary, edit the settings for a proxy server in edt\curl\_curlrc. For trouble shooting see the section installation and configuration. Take special note on the remarks about temporary files in Windows XP
   3. Mark all installed files and subfolders as 'Read only'
   4. Import the registry file edt.reg in the EDT folder, that was created during installation, on the other clients.
      (Note: this requires that the drive letter of the network drive is identical on all clients, otherwise you have to edit HKEY_CLASSES_ROOT\EDT file\shell\open\command accordingly)
4. When you need to install on a new version, only the software on the server needs to be updated
5. When and what executable connects to the internet when I run EDT?
   Data is sent and retrieved by C:\Program Files\edt\curl\curl.exe over HTTP. Data is only exchanged at the start and at the end of the program. No data is exchanged during the program session
6. To what port and internet server does EDT connect to?
   EDT only connects to the internet over HTTP (port 80). When no connection can be established, EDT will report the URL that was requested. The web server the EDT connects to, depends on the version of the Argo LMS your organisation uses.
   When EDT is started by running simulator.exe directly and then logging in as a student, your organisation runs Argo version 2 or 3. In this case EDT connects to edtfile.electude.com.
   When EDT is started by clicking a simulation in the browser, after the student or teacher is logged on the the Argo LMS, your organisation uses version 4 of higher. In this case EDT connects to the same server as the Argo site (e.g. yourschool.electude.com)
7. Where are temporary files stored?
   In Windows XP temporary files are stored in C:\Windows\Temp\edt. In Windows Vista the location depends on the name of the user, e.g.: C:\Users\Username\AppData\Local\Temp\edt.
   You can change these locations by modifying the TEMP variable in this registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Environment
