hi, sorry but this is obviously not the place for chrome installation support - you'll find them at https://support.google.com/chrome

Also, your Firefox identified itself to the forum as version 45.4.0esr. An update is available: this article describes how to get Firefox 52.2.0esr using the "About Firefox" dialog on the help menu: [[Update Firefox to the latest version]]. If something is holding you back from upgrading to Firefox 52esr, please let us know so we can suggest solutions or workarounds. Version 45.4.0 is not secure; Mozilla discloses [https://www.mozilla.org/security/known-vulnerabilities/firefox.html security flaws] after each new release.
