This error may occur if you are seeking to use LVCompare with an unsupported LabVIEW edition.

In LabVIEW 2021 and prior versions, LVCompare.exe requires LabVIEW Professional Development System. As of LabVIEW 2022 Q3, these methods are available for all LabVIEW editions - Base, Full, and Professional Development System.
Follow guidance in Missing LabVIEW Compare VIs and Merge VIs Tools to ensure you have a supported LabVIEW version for the LVCompare.exe tool

If you have confirmed that you are using a supported LabVIEW version, updating Windows may solve your issue.

Check for Windows updates. If available, install updates and reboot the computer. before trying LVCompare.exe again
