I accidentally uninstalled Audacity and can’t use system restore to get it back. Tried to login to Audacity but message keeps saying username is wrong. Don’t remember username or password. How can I login?
Audacity does not have a log-in 
You can download the latest version of Audacity by following the links from this page: Audacity ® | Download for Windows
The link will take you to FossHub (our download partner). Left click on the text link on the FossHub page “Audacity Windows Installer” to start the download. (The download is typically very fast).
