lol .. that just happened to be the version at the time I did the sample image which is irrelevant. Take a closer look at the image, lower left (2nd attachment) .. where it points to the Classic versions link underlined in RED. You wanted to downgrade to the older Pro 4.18 version right? Then on your Pro download page, click the Classic link on the left hand side. That will take you to the out of date Pro installers.
