I've been struggling with the Nessus (personal version) installation since when I do : "dpkg -i file_name" it gives me a different launching command to start it than the "common", I use it and nothing happens, I Also used the common one /etc/init.d/nessusd start and throws me error. What Can I do?

Thanks In advance,

Screen shots attached
*In case that you wonder, I changed the file's name from the orig to just Nessus
*Nessus itself asked me to start it by entering /bin/systemctl start nessusd.service
