Old Version Opens

I downloaded v. 2.2.2 but when I open some of my files, they open with v. 2.1.1! What’s up with that? Why don’t they open in v. 2.2.2? Is it a problem?

Try uninstalling Audacity completely from your computer, then reinstall Audacity 2.2.2.
Ensure that you download the official version of Audacity via the Audacity website: https://www.audacityteam.org/download/windows/ (Audacity 2.2.2 installer)

I open some of my files

Just some of them?

Does Windows have a setting where you can tell it what to use?
