Optionally since the program is natively in English you can open the folder where it is installed and delete the Lang folder. Not sure if that will give some error on launching CCleaner or not since the language preference would be in the settings.
If your installer launches in a non-English language, and it is not the language of your operating system - do not complete the installation. The installer is not ours.

Where did you download it from?

Try installing the SLIM build from here,

Does that work ok ?

Thanks hazelnut,

Your linked slim version installed perfectly.

The first option in the installer was to select my language preference. That option never appeared in the troublesome versions that I downloaded from <a href="https://www.ccleaner.com/ccleaner/download/standard" rel="external nofollow">https://www.ccleaner.com/ccleaner/download/standard</a> .

Thanks Andavari.
Good idea, but the bad installations never processed far enough to create working folders such as Lang.

Thanks Stephen Piriform, and others who offered suggestions!
The installer's properties seemed to me to be legitimate, but they could have been spoofed--I don't know.
