The genuine Audacity release is available via the Audacity website: https://www.audacityteam.org/download/windows/
(downloads are served by our content delivery partner FossHub).
“Audacity Windows Store Version” appears to be an old version. It is being distributed by “Blue Sky Software” without authorization. Their website falsely claims that it is their software.
Never pay for Audacity. Audacity is free open source software.
