Inssider don't start

I’ve insside 5.3.11 on my notebook.
If the notebook has non connection to internet, inssider start and close immediately with neither warning nor error message. My workaraound while doing a site survey for example on a new building, is to connect the notebook to a mobile hotspot, then open inssider and continue working.
My notebook is hp 850 G6 with windows 10 pro 2004.
Can someone help me?
Thanks in advance and best regards.

Hello sauro.cerri,

This has now been fixed in version 5.3.18! inSSIDer can now run without internet as long as you’ve logged in within 30 days.
