  10. Where is the default location of the installed CAL software application?
    • For Windows the default location of the installation is C:\ProgramFiles\CAL\. For Macs the default location of the installation is the folder \Applications\CAL\.
    • back to top

  12. Where is the default location of the shortcuts for the application?
    • For Windows the default location of shortcuts is Start->Programs->CAL. Another shortcut is also placed on the desktop. For MAC users a shortcut to the application is placed on the desktop. A shortcut will also be placed in the folder \Applications\CAL\.
    • back to top

  14. Once installed, how do I run the CAL software?
    • In Windows, click the CAL shortcut on your desktop or use the CAL shortcut on Start->Programs->CAL on the start menu. On MAC systems, click on the CAL shortcut on the desktop or in the folder \Applications\CAL. Note that technical staff may decide to create shortcuts in different locations, in which case you need to instruct your students where to find the shortcuts in order to launch the CAL application.

  18. Where do I find, and how do I run the Preferences program?
    • For Windows users go to Start->Programs->CAL-> Preferences. On MAC systems go to the Preferences program located in the folder \Applications\CAL.
    • back to top

  20. How do I enable the Speech feature of CAL?
    • First make sure that your systems meet the minimum system requirements to run the speech feature. To enable the speech feature in CAL follow these steps:
      • Open the CAL Preferences program.
      • Select the "Speech Settings" tab.
      • Enable the speech feature by selecting the speech check box and saving changes.
    • back to top

  22. Does CAL support Proxy servers and proxy server authentication?
    • Yes, the use of proxy servers and proxy server authentication is supported by the CAL software. CAL tries to automatically detect and use the proxy setting configured in your computer. In Windows systems the proxy settings are retrieved from the Windows registry: HKEY.CURRENT_USER\\Software\ \Microsoft\\Windows\\CurrentVersion\\Internet Settings\\ProxyEnable and ProxyServer. If these values are not set, you will need to manually set the proxy setting using the "Preferences" program. In Mac OSX systems the proxy settings are retrieved from the Network manager. In most cases you will not need to worry about proxy settings, but if you need to manually edit them, follow these steps:
      1. Locate and open the Preferences program.
      2. In the Proxy Tab check "HTTP Proxy" box and fill in the http proxy host and proxy port (contact your system administrators to obtain this information).
      3. If you use a different proxy server for SSL communication, select the "Secure Proxy (HTTPS)" box and fill in the corresponding proxy host and proxy port (contact your system administrators to obtain this information).
      4. Click Apply or Ok.

  24. What are the "Debug" and "Log File" panels in the Preferences Program?
    • The Debug panel helps you troubleshoot problems with the CAL software. There are five different tests that are run to verify if your system is ready for CAL testing. The following are the tests available and possible actions to take in case of the test failure:
      1. Writing to Local File System: CAL application writes log messages to a file in the local file system: \.cal\cal.log, (for instance for Windows this is C:\Documents and Settings\\.cal\cal.log). This test tests if there are sufficient permissions for writing to this file. The failure of this test is not critical since CAL will still run, but messages will not be logged into the log file.
      2. DNS Tests:
        • Domain Name Lookup: This tests if there are any problems with CAL software locating your DNS server.
        • CAL Domain Name Lookup: This tests if your computer can reach the CAL central data servers by their domain name.
        • The passing of the above tests is critical for the correct operation of the CAL application. A failure indicates that there is a problem with the DNS servers at the schools and/or at the CAL servers. If you determine that this situation is not a local DNS problem, you will need to contact us.
      4. Connectivity Tests:
        • General Internet Connectivity: This tests if the schools are able to connect to the internet, which is essential for connecting to CAL central data center.
        • CAL Internet Connectivity: This tests if your computer is able to connect, in particular, to CAL servers.
        • The passing of the above tests is critical for CAL to operate properly.
      6. Log File Panel:
        • The Log Panel displays the contents of the CAL log file (\.cal\cal.log). This file can be useful when troubleshooting the application. The panel displays at the maximum the last 500 lines of the log file.

  26. Does CAL support secure Internet communication?
    • Yes, CAL supports secure SSL communication. To set up computers to use SSL communication, follow these steps:
      1. Run the Preferences program as indicated previously.
      2. Select the Secure Connection tab.
      3. Check the Enable Secure Connection check box.
      4. Click Apply or Ok.
      5. Also make sure that your school network allows outgoing SSL communication on Port 443, and that your proxy server (if used) supports SSL communication.

  28. What port needs to be open for the CAL software to work properly?
    • You need to allow outgoing communication on port 80, and if you set up CAL to use SSL communication you will also need to allow outgoing communication on port 443.

  30. When the CAL application is opened, a new update is being deployed but it always fails.
    • You see this problem if the current user of the computer does not have privileges to update the software.
    • back to top

  32. How can I get the updates of the CAL software?
    • CAL has an automatic update feature that checks for updates every time CAL is launched. If an update is available, it will be automatically downloaded and deployed onto your computers. However, if your computers support multiple users (Windows NT, 2000, 2003, XP, MAC OS X), in order for the updates to be successfully deployed, the systems must be logged in by a user with privileges to write to the folder where the CAL software was installed (refer to question 7). The default installation of CAL sets permissions so that any user of the computer could automatically download and deploy available updates by simply running the CAL application.
    • It is important to mention that these default permission settings will also grant permissions to any user to delete or modify the CAL application. If you decide that this is not a good decision in your environment, you can manually restrict the permissions of the CAL installation folder; then, in order to get CAL updates when they become available, you will need to have a user with administrative privileges run the CAL application. There could also be systems or situations in which the default permission settings fail and users without administrative privileges will not be able to get the available updates. In this case you have three options:
      1. Manually change permissions to the CAL installation folder so that all users have permissions to download and deploy the available updates.
      2. When updates are available, have a user with administrative privileges launch the CAL application so updates are automatically deployed.
      3. Windows users can use Window Installer-based patches to automatically deploy updates using Software Installation and Active Directory Group Policy. See next question.

  36. Receiving error messages while students are testing.
    • "Unable to connect to the central server. Please check your Internet connection. Contact your teacher or test administrator."
      "Your internet connection has been lost. Contact your teacher or test administrator to reactivate your password for this part of the test."
      "A system error has occurred. Contact your teacher or test administrator."
      "A system error has occurred. Contact your teacher or test administrator to reactivate your password for this part of the test."
    • Check if you have a proper Internet connection in the computers with the problem. If your connection is good, open your browser and go to http://ifg3.caltesting.org/test.jsp to test the communication to the CAL data center. If you get a "Success!" message, then try to run CAL again and take a practice test. If you still get the same results, open the CAL Preferences program to check if the CAL proxy settings are set correctly. You can also use the Debug Panel in the Preferences program to assist you with troubleshooting the problem.

  38. What are the url(s) for the servers that the CAL software connects to?
    • These are the URLs that the CAL software needs to connect to:
      • http://ifg.caltesting.org
      • https://ifg.caltesting.org
      • http://ifg3.caltesting.org
      • https://ifg3.caltesting.org

  40. Mac 10.4 problems with a blank screen.
    • In very few situations we have experienced problems with Mac 10.4 systems randomly getting a blank screen when CAL is launched. We continue to work on a fix to this problem; but the current solution is to close the CAL application by using the X in the top corner and hitting the Enter or Return key. Then, reopen CAL again. This should clear the problem.
