Issue Details

I re-imaged my PXI controller 8135 with Windows 7 Professional (Service Pack 1) 64-bit version and installed LabVIEW 2016. When I tried to open LabVIEW 32-bit version or NI-MAX a pop-up window appear showing the following error: nierserver.exe- bad Image.
But If I open LabVIEW 64 bit it opens normally with no error.

The following is an image of the error.


Follow the next step to fix the missing .dll in the path.

  1. Search in  "C:\Program Files (x86)\National Instruments\Shared\USI\Bin\msvcr71.dll"
  2. Copy and paste  MSVRC71.dll on the Desktop.
  3. Copy and paste the  MSVRC71.dll on "C:\Windows\SysWOW64\msvcr71.dll".
  4. Restart the PXIe.
  5. Open LabVIEW 2016 (32-bit version) or NI-MAX.

Additional Information

The root of the issue is a missing .dll or corrupted.  If the .dll is already in the folder (C:\Windows\SysWOW64\) you have to overwrite the old dll with the new one.
