If you're getting a 1067 error it's possible you're getting a port conflict so the service can't start. I had this in the past when some rack monitoring software was already using one of the qlikview ports.
I used netstat to find any processes uaing particular QV ports
e.g. from the cmd line
netstat -a -n -o | findstr :4747
The far right column would then give you any process ID already using the port so you can use tasklist to find which service is using it
tasklist /FI "PID eq 2024"
If you find a conflicting port you configure the conflicted qlikview service to use an unused port.
