One-Click Install DreamHost and wp-admin/install.php page not found

Hi!

I’m a previous wordpress.com user trying to make the switch to www.ads-software.com. I had a domain registered through wordpress.com (StephanieRDN.com), and was able to transfer through the one-click install on Dreamhost (everything is unlocked and the transfer has been approved). I also changed the DNS servers to ns1.dreamhost.com, ns2.dreamhost.com, ns3.dreamhost.com.

I am struggling with the first step of an email I received. I am unable to create an admin user at: https://www.stephanierdn.com/wp-admin/install.php

It says the page is not found.

I’m so lost! Help!
