Are you only logging this info to stdout? At least I couldn't find a logfile anywhere in the factorio directory structure. I added some redirects to the batchfile, the outputs are attached.
This is on a Windows 7 SP1 x64 (it's actually an office machine, a Dell Optiplex ). If you need any more details, I'll be happy to provide them.
