There is a known issue with the LabVIEW 2018 FPGA Module Xilinx Compile Tools for Vivado 2017.2 that only affects Windows 10 version 1709 or later. A patch was released to address this issue as was distributed via NI Update Service. The patch is also included with the LabVIEW 2018 FPGA Module Xilinx Compile Tools for Vivado 2017.2 installer but is only installed if the installer detects that the Windows 10 version is 1709 or later.
Because the patch is included with the installer, this behavior should only occur if the Vivado 2017.2 compile tools were installed on an older version of Windows 10 that was then updated to version 1709 or later. Please refer to LabVIEW 2018 FPGA Module Patch for Vivado 2017.2 on Windows 10 1709
for more information.
