You could run jv16PT 2012 in DEBUG mode: Press Ctrl+Shift after the start of jv16PT, to be followed by a restart of jv16PT.
DEBUG mode produces a Debuglog.html shortcut on your desktop. This Debuglog file is refreshed every time you restart jv16PT.
After a Registry Cleaner scan run which (randomly) has stopped, please attach the zipped debuglog.html file to this forum thread.
Because Windows 8 is not yet an official product I do not know if the developer (jv16) will analyze this attached Debuglog.html file
