This is the stock 2.3.1 without any add-ons.
This is a copy of the download available from the OSC site and as such is free If you need any stock files for any reason this could be the place for you.
Once you have placed the order if you are not buying any other services I'll have to approve the "payment" before the download link will appear on the order history screen.
So please be patient.
Once you have installed this version you will need to check github for updates and then install the add-ons you want.
