Need help installing Miniconda

I am about to start the first off-Codecademy project in Python 3. I installed Python 3 from this article - Installing Python 3 and Python Packages.

That article also describes how to install Miniconda. I am unable to do so. I went to this page linked in the article. I downloaded both ending in pkg. I clicked through the installer. At one point it says, " “Installer” wants access to control “SystemUIServer”. Allowing control will provide access to documents and data in “SystemUIServer”, and to perform actions within that app." I said OK. Then it says “Miniconda3 is already installed in /Users/jon/opt/miniconda3. Use ‘conda update miniconda3’ to update Miniconda3.” I went to that part of my computer and clicked on conda.exe. It says “You can’t open the application “conda.exe” because Microsoft Windows applications are not supported on macOS.”

That is where I am. Thank you for any help.

Never mind. I figured it out.
