Missing NIIMAQdx.dll in LabVIEW

Issue Details

I am using NI-IMAQdx VIs in LabVIEW and I get one of the following errors:

The library specified for this node cannot be found or cannot be loaded. Right-click the Call Library Function node and select Configure, then choose the correct library name or path.

OR

Error -1074360284 occured at an unidentified location
Possible reasin(s): 
NI-IMAQdx: (Hey 0xBFF69024) DLL Could not be found.

OR

LabVIEW: (Hex 0xF) resource not found. 
Niimaqdx.dll 
An error occurred loading VI 'NI_Vision_Acquisition_Software.lvlib:IMAQdx Close Camera.vi'

Solution

1. Download the vision acquisition software from the NI website (make sure you select the version that is compatible with your current setup). More information here: Missing NI-IMAQ or NI-IMAQdx Functions Palette in LabVIEW
2. Force reinstall the software by following the instructions in Force Reinstall Non-Working or Corrupt NI Software.
3. If the issue still persists, check the DLL version of niimaqdx.dll in 'C:\Windows\System32' and 'C:\Windows\SysWOW64'. Make sure it matches with the version of NI-IMAQdx you have installed. You can check the version of the DLL by right-clicking on it and select Properties. The details tab will contain the DLL version.

Additional Information

Usually, this error will come because of the following reasons:

• The software is not loaded in the computer (it has not been installed, or the current installation is not compatible with your environment).
• The software is corrupted because of a bad download, installation or hard drive damage.
• The software has not been licensed properly.
• Software uninstall of a previous version of NI-IMAQdx left 'niimaqdx.dll' behind because it was in use at the time of the uninstall. A new NI-IMAQdx installation would not overwrite these files and hence, we end up with a version mismatch.
