Well this becomes a bit complicated to me.
To try and see with another computer, I installed it on my old HP Pavilion laptop (2009) with Windows 8.1.
The update of CCleaner did not propose me to install the browser. I looked for it manually and downloaded it from cdn-download-ccleanerbrowser.com and installed it. The optional installation window did not show like the first one I received before on my desktop ; and after refusing the import of data from Firefox, the result is here correct.
Attached the txt file with reports from both my desktop (which has a m.b. from Asus dated... 2006 and working perfectly also with Win 8.1) and my laptop.
I stop here my participation in your quality cirle, as I think that a software must be at my service, and not the contrary.
Thank you for your understanding.
