FileZilla has the following offer in place and neither checkbox is unchecked at the moment, I nearly missed it myself as I didn't expect it to be in such a popular software.
The class window inside the installer is: "Internet Explorer_Server".
I cannot find any classes for the two checkboxes however their coords relative to the class window is:
Checkbox 1: 25, 150
Checkbox 2: 10, 200
Their coordinates relative to the installer window is:
Checkbox 1: 38, 238
Checkbox 2: 38, 238
I'm not at home so I cannot easily provide the URL of the internet explorer page
