Native Messaging
Native messaging enables an extension to exchange messages with a native application, installed on the user's computer. The native messaging serves the extensions without additional accesses over the web.
LanSchool Air uses a native messaging host for the Edge and Chrome extensions.
LanSchool Air Native Messaging- Tab Viewing is Not Working
If tab viewing is not working and the extension is installed there may be an issue with the Native Messaging host.
Check Running Processes
Confirm WinNativeHostMessagingHost and WinNativeHostMessagingClient processes are running in Task Manager on the student device.
If one of these processes are not running check your antivirus. Some antiviruses will detect WinNativeHostMessagingClient.exe as a browser exploit and delete it from the computer.
Confirm that the WinNativeMessagingServer process is running in Task Manager on the student device.
If any of these processes are not running and are not being blocked by antivirus, please see the following solution(s).
