I found out that my issue was related to the CLI not liking the fact that my files were stored on a seperate drive than the PDF24 install drive. Was able to remedy my issue by adjusting my script to move all files into a temp folder on same drive as PDF24 install, OCR them, then ship them where they needed to go. Unsure if you're experiencing same issue, but I can try and help troubleshoot if you give some more information?
