Issue Details

After following the installation instructions in Product Manuals: CAN Frame to Channel Conversion Library the palette shows up but the VIs cannot be found and show up as question marks.


The API.llb library included in the download is not named correctly. All VIs are looking for a library named FCCL.llb.
  1. Follow the instructions as listed in the User Guide but change the name of API.llb to FCCL.llb
  2. After restarting LabVIEW you should then be able to find the VIs in the palette in LabVIEW.
  3. You may be warned that the file location has changed, if this happens, open the so that all the VIs in the palette are in memory then close LabVIEW.
  4. You will be asked to save changes to all VIs in the library. After clicking yes you should be able to use the VIs with no further trouble.
