Is there a timelimit on the QlikView server license you're using?
In my experience the most common issues with the QlikView Server service not starting is because of license issues. I would suggest getting in touch with QlikView support who should be able to help you out with any license issues.
"Many of the actions performed by the QlikView services, requires lookup of user credentials, therefore they need to be run via a domain account. Contrary to how it worked in 8.x." (quoted from guerrillabi.com)
I changed to a domain account and then it started.
