We are on SharePoint 2013 & Workflow version 220.127.116.11. I'm attempting to update to Workflow 18.104.22.168.
I stopped the Nintex Workflow Start service and started the installer. It took several hours and there was an error, "Job(s) was/were never created for solution Nintex Common Components (NintexCommon.wsp) upgrade, waited for 3600 seconds". The Nintex Workflow Licensing page says I am still on version 22.214.171.124. There are no errors on the Solution Management page. So I think the install didn't do anything.
I read in the form here that the installer would run faster if you clear the SharePoint Config Cache first. I did that and ran installer again. It was not faster; I got the same error and the Licensing page still says 126.96.36.199.
What should I do?
