darktable-cli fails

I’m trying to use darktable-cli (windows) in its most simple form to process the images in one folder and put the output in another folder.

I start darktable with a BAT-file containing the following commands:

@echo off

C:“Program Files”\darktable\bin\darktable-cli C:\foto\DT.develop.in C:\foto\DT.develop.out

This command fails and results in the following error log (why isn’t it visible using file explorer?):
