I followed the download directions and it went fine except that the computer identifies the download as a removable storage device and isn't giving me anything to install or run. What do I do now?

I never got an error message while attempting to download and install LibreOffice on my Mac laptop, which I only recently acquired and don’t know very much about. The download completed without obvious issue but now does not show up on the desktop where I left the icon it provided. When I tried to follow the installation directions, I could not find anything in the download that would install or run. I would very much like to enjoy using LibreOffice as I have successfully for nearly a year on my desktop computer (which runs a Linux OS), but I don’t know what to do now.

Did you use these installation instructions?
