However, running VRS ends up with the error message below.
What am I ding wrong?
Confirmed many times port 80 is not occupied on my server:Cannot start the web server on port 80
If the web server cannot start because another program is listening to the port
then run the Virtual Radar Server installer again and choose a different port.
