How exactly Comodo knows users IP

When I download CIS installer and run it, it always is on my own language (which isn’t English). So I have a question: how Comodo determines my language?

Most likely by looking at the language and regional settings of your Windows installation. Another possibility would be to look at your IP address and cross reference it with online IP address databases But I must admit I never looked into this.

language and regional settings…I forgot about this completely. So it must be system locale which Comodo installer is looking at, because my Windows installation is English. Thanks for the explanation Eric.
