I suspect not ... yet ;)

I mean "take advantage of". Like the latest defraggler just began to take advantage of 64-bit. "New native 64-bit EXE." (Defraggler changelog quote)

Hence my reply ... there is no native 64-bit version of CCleaner that I am aware of.

Well then, that's one for the developers. I think that a 64 bit version is needed. But I'd like to see an all in on package with all the products contained (Ccleaner, Defraggler, Recuva and speccy); but tailored specifically for 64 bit.

It does work on 64bit computers, it just doesn't have a dedicated 64bit executable.

Which is why the answer to the OP's question is 'no'. Whether a or not the 32-bit exe works on a 64-bit machine is a completely different question.
