In my company we use the free version and so I monitor the version number and, incidentally the file size, to know when there's a new version. I downloaded and installed 4.19... on 27 Oct. On 3 Nov I got a message from my monitoring program that the file size had changed although the version number hadn't.
I downloaded the installer again and it is 1592 bytes bigger than the file I downloaded in Oct. I was suspicioius but eventually tried installing it. It wouldn't install.!: As I maintain this for my company I need to know if this version was correct.
It started installing but after the green bar moved about 1 centimetre it stopped. The only way to stop it was to use Task Manager.
How has this happened? Will it be corrected? Are the others in my company stuck with 4.18 until version 5 comes out?
Is CCleaner secure and can we trust it?
