Hello Shaun,
Thank you for the provided resources!
After further investigating this, I found the culpirt here.
Basically, your .BAT file is relative to the "Chronicall" folder. As a working directory, you only give the [APPDIR], without the folder.
Basically, the .BAT file will try to search for the "bin" folder under the APPDIR folder, where it does not exist.
To fix this, please change the working directory to:
[APPDIR]Chronicall
Hope that helps!
Best regards,
Catalin
