    we use enterprise Chrome installer, which makes sane choices for most things
    the installer will run successfully whilst Chrome is running, installing to new_chrome.exe
    when the last running instance of Chrome exits, then:
    chrome.exe is renamed to old_chrome.exe
    new_chrome.exe is renamed to chrome.exe
 
    chrome installer log is at
    %temp%\chrome_installer.log
