Issue Details

I am unable to open or save a DBC file in NI-XNET Database Editor.
 
When opening a DBC file, I receive the following error:
 

An internal error occurred. Please contact NI and provide the logs found in "%LOCALAPPDATA%\National Instruments\NI-XNET\log". 

 

 

In some cases, when saving a DBC file, NI-XNET Database Editor returns the following error:
 
NI-XNET: (HEX 0xBFF63132): Creating a database file failed. Solution: Verify access rights to the destination directory or check if overwritten file has read only permission.
 

Solution

Check whether the DBC file is stored in a file path that contains Japanese characters. When using the new NI-XNET Database Editor, ensure that the full file path (including folder names) does not contain Japanese or non-ASCII characters, as this may prevent the file from opening.

 

As a workaround, you can either:

  • Move the DBC file to a directory with only ASCII characters in the path
  • Use the classic NI-XNET Database Editor, which supports such paths
    • The classic editor can be launched from the following location: C:\Program Files (x86)\National Instruments\NI-XNET\editor\XNetDbEd.exe
