We just recently tried to upgrade from an older version of LanSweeper to a new one but it had a whole lot of issues so we reverted back. Everything appears to work except helpdesk gives an error saying "The file '/helpdesk/helpdesk.master' does not exist." I have had this issue before and was able to stop all the services, install the website again and then load it all back up and it works but so far that has not helped here.
Even during installing the website I have seen helpdesk.master on the installer but it does not actually appear to be installing.
I emailed support but figured I would post here as well.
