Thanks, Nergal, that is exactly what I did. They are working on it.

I have exactly the same problem for my 64b Windows 10 family desktop PC. As indicated above, the rest of CCleaner is operating properly but when I attempt to use the Disk Analyzer function, it fails to open and ultimately closes down the entire program. I purchased CCleaner because the program includes a Disk Analyzer function. So I'm not a happy camper... especially if it can't be fixed.
