Please rephrase your question. It is not at all clear what it is you're trying to accomplish.

You are using InstallOptions but not nsDialogs, you write "Title=nsDialogs::Create 1018" yet. I don't know whether you how nsDialogs use. However, no matter what you are using, you can send a message to the checkbox to uncheck it depending another checkbox's state.
SendMessage $hwnd_botton ${BM_SETCHECK} ${BST_CHECKED} 0
SendMessage $hwnd_botton ${BM_SETCHECK} ${BST_UNCHECKED} 0
You can read the handle of controls from ini file's HWND value of each field after the dialog has been initialized, and them using SendMessage to control them.
