Hi there!
What that setting means is where the client executable will be executaed from. If it is set to Local, it will run a copy in automation folder on that machine. If remote, it will run it from the mapped eXpress share. My recommendation is that you keep that set to Remote. This way, the automation client will always run the latest version from that mapped location on the server. Otherwise, the automation client ran will be the one in the automation folder, and for that client to be updated, a new automation folders package will need to be distributed each time an update is done.
Thank you,
