I followed this guide to setup Wintermelon: https://www.ilovefreesoftware.com/16/windows/how-to-show-lock-screen-on-both-displays-in-dual-monitor-set-up.html, trying twice with the files in Program Files and in Downloads with no luck.

The tasks point to the correct location of the exe as well, but the lock screen still only shows on one monitor.
