Piriform support has confirmed the random design of the installation. I've told them that in the case of two purchases they should give the customer the choice of which installation gets the beta version. However, the randomness is probably not amenable to that approach. The problem for Piriform is that they won't be getting much feedback from me because it installed on the very rarely used old computer. I only turn it on daily to get security software updates, whereas I use my other computer every waking minute, and use CCleaner Professional probably a dozen times a day.
