Currently you can not operate EWF settings remotely on Scala PC Players. (SUP-1810 Unable to run EWFMGR.exe command from maintenance job). However, if you install PsExec.exe, you are able to do it. You must test it before integrating on many players. A tech team is working on without installing the PsExec file (From 12.00?).
Below example is for Scala Ready PC PC Players.
