...and (sorry about not making that clear): the curly braces in the parameter must not be entered; they were just there to mark
scenarioPath as being a variable.
So your command line would be:
C:\Orbiter2016\Modules\Server\orbiter.exe -s "C:\Orbiter2016\Scenarios\$CH-5%.scn".
If this is executed in your working directory (
C:\Orbiter2016), it should start Orbiter as expected.
In "batch-file" style this would be:
Code:
cd C:\Orbiter2016
C:\Orbiter2016\Modules\Server\orbiter.exe -s "C:\Orbiter2016\Scenarios\$CH-5%.scn"
