Issue Details

  • I formatted my computer to Windows 7 and installed LabVIEW 2014 and NI-DAQmx 18.0.0 to use my PCI-6040E.
  • When I conected the PCI to the computer, it didn't recognize it.


     The driver isn't working as expected because of compatibility. Before download any NI driver, read the 'readme.txt' file that is available in the driver download page. This driver document shows a list of supportted versions of LabVIEW. If you check that the newest version of a driver isn't supportted by your LabVIEW version, try to look for a old version of the driver.  

     Here is an example of a table of compatibily between drivers and LabVIEW versions:
Application Software Versions Supported by NI-DAQmx
Application SoftwareVersions Supported by NI-DAQmx 17.6Versions Supported by NI-DAQmx 18.0
2014, 2015, 2016, and 20172015, 2016, 2017, and 2018

Measurement Studio2012, 2013, and 20152012, 2013, and 2015
SignalExpress2014 and 20152015

Make sure to install a driver that is compatible with your LabVIEW version. 

Additional Information

Beyond the relation of compatibility between an NI software and a driver, you must consider the Operational System and its version. The 'ReadMe' document also brings information about which OS are supportted by a driver.
