This morning I installed powerJobs 19.0.7 for Vault 2019, onto a Job Processor workstation running Windows 7 SP1
When it starts up, the following errors appear in the console & in powerJobs.log
2019-06-21 13:32:37,430  INFO PowerJobProcessor.App - Starting coolorange PowerJobProcessor 18.104.22.16866 2019-06-21 13:32:37,648  ERROR powerJobs.Common.JobFactory - System.NullReferenceException: Object reference not set to an instance of an object. at powerJobs.Common.JobFactory.GetJobs()
The full log is attached
Have you any ideas about what could be the issue?
Looks like it might be fixed, and was caused by some partially installed Windows updates
A few updates/restarts got to the point where this was happening
After making the changes suggested in the post, it's all OK
