This post walks through installing Vivado HL Design Edition with support for all Xilinx devices and installing the Xilinx SDK using the Download and Install Now option. It was written on May 6th, 2020.
Get and Start the Installer
These steps can be used regardless of how you got or started the installation.
To find and start the Windows Self Extracting Web Installer installer click:
Prerequisites
You have a total of 76.76 GB disk free (16.32 GB for the download and 60.44 GB for the installation). Note: using these steps, the installer will leave only 30.14 GB installed. You could download the full image to an external drive and then run the installer and install Vivado onto your main drive if you don't have space for the download and the disk space required during installation on your main drive.
You've downloaded and have started a Vivado 2019.1 Installer.
A Xilinx login. Get one at [https://login.xilinx.com/] (click the Create Account button).
A Vivado license. After getting a login, get one at [https://www.xilinx.com/getlicense]. You should have downloaded your Xilinx.lic file.

Step 7:
WAIT!!! If you're Installing as an elevated "local" user (your IT department may have you install as an elevated local computer Windows user) click All users before clicking Next. If you don't do this, when you run Vivado as your "normal" logged-in user it won't work and you will have to uninstall and reinstall Vivado with this option checked since you can't correct this.
If you have no idea what I'm warning against, accept the defaults (provided nothing is red) and click Next
