Get rid of Ncentral Windows Agent via Script

Hi,

I need to uninstall 400+ NCentral WIndows Agents that have been migrated to Datto RMM. I don't know how but i can't get this ** software removed from the system. None of their KB articles seems to be working.

Tried uninstalling via msiexec /x {GUID} /qn but also without any success..

Anyone knows the magic key to get rid of this ** software?
