I've found some of the versions at another "filehistory"-website, also the slim-ones. For your notice the version the old machine is able to run is 5.26.5937. After this there must be a codechange that prevents the old AMD-embedded-CPU from running ccleaner.
But it is not ccleaner itself that is detected but what comes with it. It should only be detected if you have enabled potentially unsafe applications in ESET. But you can also use exclusions if you like. I don't know what they bundled now as I only use the Slim build, in the past I have heard they bundled a Google Toolbar among other things.
