I installed Catalina on my 2012 Mac Mini. But it has not replaced my old program. How do I get my Mini to do that?
Mac mini, macOS 10.14
Double-click the installer. It should be located in your Applications folder.
I should probably add this warning:
! Before you upgrade to Catalina:
What you need to know before upgrading to macOS Catalina:
Before you upgrade to Catalina, please look at this Apple Support document. Specifically check that your Macintosh is on the list of compatible computers.

You should also be aware that any 32-bit apps that you are currently using will be incompatible with Catalina. (Apple software is pretty typically unaffected because the included apps are Catalina-ready or updates available for download from the Mac App Store)
You can check which of your current apps are 32-bit by clicking Apple menu >System Preferences > About This Mac > System Report.
Then scroll down the list on the left to <Software> and click <Applications> (you may have to click the triangle next to Software). It may take a moment, but shortly your Mac will display a list of the apps installed on your computer. You can then click the column labeled 64-Bit (Intel) and sort them by Yes/No.
Any apps that are listed as No in the 64-bit column will not work under Catalina.
This detail has tripped up many users who have upgraded to Catalina and then find their software is broken.
Optionally, to check for 32-bit apps, you can use the free app Go64. – it’s a compatibility scanner from St. Claire Software.
In addition to the excellent advice and tips provided by D.I. Johnson.
It is wise to have a good backup, just in case there is a problem or you need to roll back to Mojave.

I wanted to thank D.I.Johnson for his help with my Catalina download question. His instructions were clear and solved my problem.
