I have tested this on a Windows 7 32-bit system.
I have merged the registry entries listed here into Windows Registry. The merged data belongs to Avira Internet Security Suite, CA Internet Security Suite, DivX 8, Roxio Creator, Freemake Video Converter, CleanMyPC Registry Cleaner and Glary Utilities. All of these mentioned programs were NEVER installed on this system. Your registry cleaner was able to find only 1 error (highlighted one) from all the merged entries. I tried Auslogics Registry Cleaner and Ace Utilities Registry Cleaner, both the programs were able to detect all these errors.
The data was merged into the sections where your registry cleaner claims that it scans to find errors.
For example:
CLSID
Interface
TypeLib
Uninstall section
Enum\Root (drivers)
Eventlog
Services
