We seem to be confused with the versioning of Desktop Central MSP or at the very least the production version.

Have an on prem installation which is 10.1.2138.9 however your service pack latest shows Build 10.1.2137.14, both state that its on latest version however your new download on the website is 10.1.22110.2. Had tested 10.1.22110.1 which is also saying its on the latest version with no upgrade to .2

We have also noticed whilst testing from 10.1.22110.1 that it is best practice/security to delete the default admin account however since this version one does not have the ability to create a new user as the button is greyed out.
