Norton Utilities 15.0.0.124 Registry Scan Hangs

Norton Utilities 15.0.0.124 fails to complete the "clean registry" scan.

When running NU 15.0.0.124 on my Lenovo W500, Windows7 Pro, SP1, 32-bit the

registry scan hangs when reaching "custom controls" portion of the scan.

Each time the scan gets stuck at the same registry spot;

HKEY_CLASSES_ROOT\CLSID\{A8040703-2640-48B7-96CD-BC8108A4E8F1}\TypeLib

Pointing to this: to \system32\puiobj.dll.

puiobj.dll is a DLL file which is responsible for component PrintUI Objects DLL in Windows systems like Windows 7 Professional Edition 

I have tried running NU 15 in Windows  7 safe mode (no network) to no avail.

 

Any help on how to resolve or why NU 15 registry scan is hanging on the registry key is appreciated.

(FYI. I also run Norton 360 v21.6.0.32)
