CCleaner v.5 not working

I am on Windows 8.1 64 bits.



I downloaded and installed the latest CCleaner v.5 (64 bits) yesterday (2014-11-25).



The cleaning mode took an unusually long time to scan.

When the analyse results were finally displayed, the program itself stopped responding. Had to kill the program with Task Monitor.



I tried again a few times to no avail. Had to uninstall CCleaner v.5.



I have been using CCleaner for a very long time.

This is a first !!
