I am trying to upgrade Nintex Workflow 2013 to the latest version. I have ensured all services are running required for the installation by following the steps by Wisam Fawzi.
Now, when the run the Nintex Workflow 2013 Installer in the server hosting Central Admin, it gets stuck in Updating Solution Core Components > Upgrade job for solution Core Components (NintexWorkflow2013Core.wsp) is not created yet (time waiting = x seconds)
After an hour, it throws an error "Job(s) was/were never created for solution Core Components (NintexWorkflow2013Core.wsp) upgrade, waited for 3600 seconds. One or more errors were detected. Please scroll up for details." (screenshot below). There is no details listed above.
Can somebody guide me how this can be resolved? Any guidance will be highly appreciated.
