Issue Details

I installed the NI Vehicle Communication Toolkit (VCOM) and attempted to read an XML file in my LabVIEW program. When executing Start Session.vi, I receive the error -2147224705. The error occurs consistently when loading the XML file.

Solution

This error can occur due to a mismatch between the bitness of the DLL specified in the XML file and the bitness of LabVIEW being used.
 
To resolve the issue:
  1. Identify the DLL specified under the NIXNET Custom Interface section in the XML file.
  2. Verify the build bitness of the DLL:
    1. If the DLL is built for 32-bit, use LabVIEW 32-bit.
    2. If the DLL is built for 64-bit, use LabVIEW 64-bit.
