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?
You shouldn't be using CCleaner Free in a commercial environment - it's not allowed as per the EULA. If you want to use CCleaner in a business then you need to buy a business license from Piriform.
Ok, so I used "company" in a loose way - we're not in a commercial environment. Does this mean that CCleaner should suddenly stop working? Any way I'm more concerned with the possibility that the piriform site is compromised, wouldn't you be?
