Files for the public (mostly Voyager programs)


You must select the verson of each Voyager program that matches the build of the BatchCat interface for your verson of Voyager. Use these instructions to help you identify the proper verson

  1. Using My Computer or the Windows Explorer, navigate to the c:\voyager\system folder; if this folder doesn't exist, navigate to the c:\windows\system32 folder. (Depends on your version of Voyager.)
  2. Find the file 'BatchCatxxxxx.DLL' that matches your current Voyager version. ('xxxxxx' represents the Voyager version number; for example: BatchCat2001-21.DLL works with Voyager version 2001.2.1) There may be more than one 'BatchCat' file in this folder; the only relevant one is the one for your Voyager version.
  3. Right-click on the file name.
  4. Select 'Properties' from the pop-up context menu.
  5. Select the 'Version' tab on the Properties panel.
  6. The verson number is the first item on this tab. Ignore any internal elements that are zero (read '2001.11.0.1931' as '2001.11.1931').
