Collecting Logs from Student Devices

Collecting Logs from Student Devices

Overview

To assist in troubleshooting, LanSchool Support may require you to enable logging on your LanSchool.

While every attempt is made to prevent errors, with any type of software it is possible to get an error or bug. On the Windows Operating System, those errors can result in crashes, faults and error messages. At LanSchool, those types of errors are given the highest priority.

The ability to read and write the Windows Registry is required. It is recommended to contact your local IT Support to setup logging.

Enabling Logging on Windows Student Device

  1. Run regedit.exe on your computer
  2. Browse to HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\LanSchool for 64bit.  HKEY_LOCAL_MACHINE\SOFTWARE\LanSchool for 32bit.
  3. Click Edit>>New>>DWORD (32-bit) Value
  4. Name the value DebugTrace
  5. Double click on the word DebugTrace and set the value to 1 (hexidecimal).

Creating a Memory Dump on Windows Student Device

If the LanSchool Student Application is crashing, you may see a dialog box appear that looks like this.



However, it is possible no message is displayed and the application icon will only vanish from the Desktop or System Tray.
The following steps will show you how to configure the Windows Student device to generate a memory dump file. This large data file will contain a "snapshot" of the LanSchool Student Application at the moment of the error.
  1. Run regedit.exe on your computer
  2. Browse to HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\LanSchool for 64bit.  HKEY_LOCAL_MACHINE\SOFTWARE\LanSchool for 32bit.
  3. Click Edit>>New>>String Value.
  4. The string name should be MiniDump
  5. In the MiniDump string value type in a path where the logged-in user will have sufficient rights to create a new file. In the following example, "C:\Users\dddogget\AppData\Local\Temp" was chosen. 
    NOTE: You must specify an existing folder, LanSchool will NOT create a new folder for this file.
  6. After the value path has been created, reboot the machine.
  7. LanSchool will notify you when an error has occurred.
  8. After the error occurs, browse to the path created in the registry key. Locate the file lsk*.dmp
  9. "Zip" up the file and email it to Lenovo Software Support at support@lanschool.com
NOTE: If the file is too large to send in an email, please upload it to https://upload.lenovosoftware.com/ the submit a ticket to Lenovo Software Support letting them know the file name that was uploaded.
