Hi folks: I have a question about version numbers. It seems to me that CCleaner is offering a LOWER version number than the ones I have installed. Is this correct, or am I reading it wrong. Below is a screen clip showing some versions. The numbers on the left are the installed versions. The numbers on the right are the version CCleaner is saying are updates. But my understanding is that a 10.1.16.* is a HIGHER version than a 10.1.1.* ... the 16 being higher than 1. Or am I wrong?
