Unable to load MIFSystemUtility DLL

[HANUMESHKUMAR]

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.

I dont know if you already found a solution and fixed your problem but I fixed mine when I encountered the same problem by going to the package installer, select the items there, and then click the repair button.

Deleting the registry key worked for me.

Hi All,

Installing NI488.2 online or offline will solve the MIFSystemUtility.dll.

Enjoy programming

I've encountered the same error today. Unfortunately, deleting the registry keys didn't help. BBut these steps worked for me:

1. Remove NI Software via NI-Packetmanager

2. Remove NI-Packetmanager

3. Delete National Instruments folder from C:\Program Files\, Program Files (X86), and C:\user\xxx\local\

4. Remove National Instruments folder (key) in registry: Local-Machine->Software->National Instruments and in Wow64Note

5. Reboot

Then I was able to install the Packetmanager and CVI Software without any error!!
