Easiest way to auto start the SE Client is to go to the Desktop tab in Desklock Setup.
Select "Replace Existing Desktop with Desklock".
Configure the 1st application by adding the client executable "C:\Program Files\Rockwell Software\RSView Enterprise\DisplayClient.exe" to the Program field.
Then add the location of your .CLI file in the Command Line Parameter Field.
Finally, choose the Automatically Run Program at Startup option.
Hope this helps.
