Issue Details

I am trying to install software through NI Package Manager but receive the error Unable to load MIFSystemUtility.DLL.
 

Solution

To solve this error, you must manually delete the MIFSystemUtility registry key.
  1. Open the Registry Editor. (In Windows 10, type regedit into the search bar and press Enter).
  2. Navigate to the following registry key: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\National Instruments\Common\Installer\MIF\MIFSystemUtility
  3. Right click the key MIFSystemUtility key in the file tree and click Delete.
After deleting the registry key, you should be able to install the software without error.

If this issue persists please contact National Instruments Technical Support .

Additional Information

This error can occur after an uninstallation of National Instruments software fails to remove the appropriate registry keys. This does not cause any problems until software must be reinstalled and certain registry values are not set as expected.
