Those are just warnings but it shows you might have a previous version that wasn't completely removed.

System has not been booted with systemd as init system (PID 1). Can't operate.

WSL does not support systemd at PID1, WSL init is PID1. To get systemd as PID1 you need to use deamonize or systemd genie, there are a handful of different tools and approaches to getting systemd to work.

Punting this to /dupe #994. It is likely azcmagent connect can be installed and made to work absent systemd, but that is more of a tips-and-tricks discussion.
