Ok, I see stdIn is the starter directory - the one where the .accdr file is located. When I remove this I get no error but the job runs for ever- stuck on 99%. The .accdr, when run directly, finishes inside 2 seconds, and the same happens with the Windows task scheduler.
I am evaluating your product to run jobs such as this for several clients so it is important that I can set them up easily. Where do we go next on this ?
