When trying to run a job with this command, "c:\SWDInstall\R&R Studio\R-4.1.2-win.exe" /verysilent, on the workstation it is run against it stops the Symantec service and it won't connect to a package server until the service is restarted.
When running this command on the machine itself it runs fine.
