Description:
If a member of staff gets a screen showing all PCs are updating but other staff are OK on that PC
Solution:
Try completely shutting down Lanschool on the PC & then try again.
To completely close Lanschool you have to do it from the menu (clicking on the X just closes the window) - in the Administer menu - Exit Teacher Console
Once Lanschool has been closed completely you will need to find it on the start menu to reopen (it won't be in the task bar)
If this doesn't fix try profile reset
