It's now May, I have just updated CCleaner on my windows 7 laptop and had exactly the problem being discussed, frozen when the program starts, with health check option displayed.
Considering the registry fix was identified in March, I fail to understand why this update has neither been updated or withdrawn.
The solution published by AnoneeMouse on the 5th of March worked for me - albeit it took me ages to work out how to edit my registry, not something I am familiar with.
Many thanks to AnoneeMouse.
