I have updated Lansweeper from version 10.4.4.4 (to latest version 10.6.1.6 suggested me by Lansweeper itself).
Update process concluded correctly, but if I go to
Configuration -> Your Lansweeper license -> Click on check for updates now
I can see that the Lansweeper Scanning Service version is still the old one: 10.4.4.4
Solved! Go to Solution.
