Libronix Update Diagnostic Logging

Libronix Update Diagnostic Logging

Libronix Update supports diagnostic logging that will generate a list of its actions for Libronix technicians to examine.


  1. Close Libronix Update and the Libronix DLS. If there was an error the last time you ran these programs, they may not have shut down properly. To ensure that they are shut down:


    • On Windows 95/98/Me, press Ctrl+Alt+Del and examine the list of programs to see if Ldls, Libsys or Update is listed. Select any copies you find and click End Task.
    • On Windows NT/2000/XP, press Ctrl+Shift+Esc to open Task Manager. Select the "Processes" tab. If LDLS.exe, LibSys.exe or Update.exe appears in the list, select it and click End Process.
  2. Open Windows Explorer and navigate to the C:\Program Files\Libronix DLS\System folder. Double click the EnableLogging.js file to run the script that will turn on logging. Click OK when prompted. If your machine does not have the folder or the EnableLogging.js file, you can download it here. Save it to your hard disk and launch it as described above. (See the Note below if Windows cannot open the file.)
  3. Run Libronix Update, performing the action that caused the problem. Once the problem has occurred, close Libronix Update.
  4. You can find the files update.log and libsys.log in the My Documents\Libronix Log Files folder.
  5. Depending on what files Update installed or attempted to install, Update may also generate Windows Installer log files. These files can also be found in the My Documents\Libronix Log Files folder and will have names like UPDATECommonSystemFilesMsi.log and UPDATELibronixUpdateMsi.log.
  6. If you are having problems running Setup.exe from an installation disc, enable logging and run Setup.exe again to generate log files. It will write the log file libronixsetup.log. If Setup.exe launches DLSSetup.exe (the installer that installs Libronix Update), it will write the log file DLSSetup.log.
  7. When you're finished logging, run the DisableLogging.js file found in the C:\Program Files\Libronix DLS\System folder. if your machine does not have this folder or the DisableLogging.js file, you can download it here. Logging causes the Libronix DLS to run slowly and can create large log files on your hard disk, so it's good to disable it for normal use. You can tell that logging is enabled when you run the Libronix DLS by the "Logging" indicator at the right end of the Libronix status bar:
    Logging status bar indicator
    If you see this indicator when running the Libronix DLS, you should disable logging as described above.

Note:  If a Windows dialog opens with the message "Windows cannot open this file" and asks "What do you want to do?," when you double-click on EnableLogging.js, follow the steps below to select a program to open it.

  1. Click Cancel in the dialog window.
  2. Open My Computer and click on Tools | Folder Options.
  3. Click on the File Types tab.
  4. Click on the New button.
  5. Type JS in the File Extension box and click the Advanced button.
  6. Choose JScript Script File from the Associated File Type drop-down list and click OK.
  7. Highlight the JS extension and look at the "Details for 'JS' extension" information next to the Change button. It should say "Opens with: Microsoft (r) Windows Based Script Host." If a different program or no program is listed there, click on Change.
  8. Select Microsoft (r) Windows Based Script Host from the Recommended or Other Programs list and click OK twice.
