Problems in "lvanlys.dll"

Hi!

I have been trying to use the example Voltage - Continuous Output.vi of USB-6451 to get an analog output, but when staring this vi it keeps showing the following information:

  • Error loading " C:\Programm Files\National Instruments\Labview2025\resource\lvanlys.dll "

I tried several way to fix this:

  • Adding the system variables MKL_DEBUG_CPU_TYPE=4;
  • Re-install Labview;
  • Repair install Labview;
  • Disable antivirus;
  • Replace the lvanlys.dll file with older version;
  • As the help window of the Call Library Function Node in the Square(Sine, Sawtooth,Triangle...) Wave.vi said, the Library name or path is " c:\dev\_r\19\eng\lv-core\lvpostprocessingd\lv_mc_x86_64\dist_x64\resource\vanlys.* ". I also created the path in my C disk and paste the vanlys.dll in.

but sadly they all didn't work 😞

What else can I do to fix this problem?
