Solution

This error is caused by problems related to the PXI card's driver. The driver may be:
  • Incorrectly installed
  • Corrupt
  • Blocked by Windows security
  • In very rare cases, modified by malicious software

Follow the steps below to resolve error 52:
  • Verify that the correct drivers have been installed.
  • Try removing and reinstalling the driver to ensure that the files are not corrupt.
  • Update your driver to the latest compatible version.
    • Check the readme document on the driver download page to determine if the latest version supports your hardware.
  • In some cases, Windows may be failing to trust the driver's digital signature. Disable Secure Boot to work around this.
