The GetUid-x64.exe file is a key-generation or hardware-identification tool used during the activation process of certain software. It must interact with low-level system files or hardware registries to generate a unique identification (UID) number. Because Windows protects these areas, the program will fail with this specific error if it is not executed with elevated "Run as administrator" rights. Steps to Resolve the Error

Months later, when a real incident hit — an endpoint exhibiting suspicious parent-child process trees and a rarely-seen credential-dumping DLL — the team moved quickly. Using the upgraded Getuid-x64, incident handlers retrieved the token metadata for the suspicious child without taking the machine offline. The metadata showed the process was running with an elevated token obtained via a living-off-the-land exploit. The team used that insight to block the associated credential at the domain controller, preventing further lateral movement.

The utility is used to generate a unique Hardware ID (UID) from your computer, which is then required to create a valid license or registry file for the software. Why Administrator Privileges are Required
