I believe I did download from Electru.org. I also believe I saw the Multi-signature wallet option. Could have seen 4 options thought they were 3.
How about a little more certainty and precision instead? You're missing sort of a lot of those.
So far you haven't confirmed that you actually downloaded your Electrum from electrum.org, which should be the only place to download it from. Do not rely on gOOgle search hits, unless you verify very carefully to click on only the one that leads you to electrum.org. We may assume your "Electru.org" is a typo, but assumptions are no certainty. And why do we need to assume something anyway?
Next crucial step before executing the downloaded file is to actually verify that your download is genuine. The steps are described on the Electrum website and there's an extensive thread in this forum, too. I'll leave it deliberately as an exercise to search for this thread in this section here.
How about you replace those "I believe" to more accurate statements, both for you and for those here who are willing to help.
From which website exactly did you download your Electrum?
Did you verify that it's genuine?
Did you install the curren version which is 4.5.5?

What other "advanced" options do you have in mind. Be more specific!
