While doing some computer maintenance, I noticed that there are two instances of Audacity 2.1.3 with the date 20/04/2017, and version 2.2.2 with the date 31/01/2019 installed on my Windows 64 bit laptop. Why or would my system require both instances to run the application? Initially I uninstalled the older version 2.1.3 with the date 20/04/2017, but that completely uninstalled Audacity from my machine? So I reinstalled the Audacity 2.2.2 executable and now I have both versions listed again in my Settings/App & Features folder? This is somewhat confusing to me, I would expect to see only the 2.2.2 version installed, and not the 2.1.3 version. Can anyone explain this to me, so I can better understand it. I did read both of the release notes for both versions, but that just seemed to confuse me even more.
Also, I also see that there is another newer released version of Audacity 2.3.0 that I have not downloaded or installed as yet. Maybe that would resolve this duplication issue that I discovered in my Settings/App & Features folder? My goal is to only have one install instance to save the the 38.8 MB that the version 2.1.3 Audacity is currently using on my hard-drive.
