Setting up dependency between QLA and Platform Server as services can be achieved by ensuring that Platform Server is dependent on QLA. To achieve this, start a command prompt as an administrator, and type:

sc config QPPServer depend= 'Quark License Administrator Server 4.5'

You can remove the dependency (if you need to in the future) with:

sc config QPPServer depend= /

(note, the space after depend= is required – also, if you want to depend on multiple services, separate them with a forward slash)
