You probably have a network path problem. Some login scripts overwrite the DOS path statements issued in the Autoexec.bat & for some reason the Batch Utilty uses one unlike other post WIN95 products. See TID #TS45375.
You should 1st make sure the folder C:\Program Files\Common Files\Autodesk Shared\ exists. If not reinstall the batch utility and or Autocad. If that doesn't work, try adding the above folder to your network path statement. You can also edit the Batch Utility Icon Properties. Right click the icon on your desktop, select the shorcut tab & enter the folder name in the Start in: box.Click apply & ok. You will need to load Autocad once before using the Batch Utility. You will then have to browse to where your drawings are.
