I am on a virtual machine with a scheduler license on it. We had a workflow scheduled that simply opened Outlook using a Text Input, Command Tool and Browse Tool that read a bat file that had the command: start outlook. This scheduled workflow ran great until I updated my version from 2018.3 to 2019.2 . Since this time, the scheduled workflow does not execute. There are no errors output in the Scheduler Results window. I can still run the workflow manually in Designer. I checked the System settings and Alteryx Scheduler is still set to Run As myself.
