How to Resolve Xilinx Compilation Error 91

Primary Software:
Primary Software Version: 8.6.1
Primary Software Fixed Version: N/A
Secondary Software: N/A
Hardware: CompactRIO

I try to compile any LabVIEW FPGA code, and I always receive the following error during the compilation:  

FATAL_ERROR: <name of library> - dll open of library
failed due to an unknown
reason. Process will terminate. For more information on this error, please
consult the Answers Database or open a WebCase with this project attached at
ERROR:Xflow - Program par returned error code 91. Aborting flow execution...

How can I resolve this error?

This issue is usually due to a corruption with link the LabVIEW FPGA module and the Xilinx compile server. The way to resolve the issue is to either:

  •  Recreate the LabVIEW FPGA target from within Measurement & Automation Explorer and LabVIEW Project Explorer.
    1. Delete the target from within the Measurement & Automation Explorer, reboot the controller, and allow MAX to re-detect the target.
    2. Manually delete the R series or CompactRIO target from the project in LabVIEW Project Explorer and re-add it.
  • If this does not work, Uninstall and Reinstall LabVIEW, LabVIEW FPGA module, and LabVIEW Real-Time module.
