You may install 32-bit builds of USEARCH on a shared university computing resource if you make sure that the binary has execute-only permissions to prevent users from making unauthorized copies (they can download their own copy here).
The email list has been discontinued. In future, I will tweet about updates and other USEARCH news such as new preprints and published papers. If you don't use twitter, you could use a service such as changedetection.com which can send you an email every time this page changes (which happens when a new version is posted, rarely for other reasons).
