Key Finder Error 1314: A Required Privilege is not held

If you get the error Error 1314: A Required Privilege is not held when using a key finder to locate your lost Windows Key off a USB Windows hard drive using the "Load Hive from a windows folder" or similar, this just means that you have to start the program with "Run as administrator" instead of the normal mode. 

To do this, right click on your key finder program and right click and say "Run as administrator". Confirm the confirmation dialog and then proceed. Now the key finder should be able to read the windows folder without any issues.
