Uninstall opmanager

Uninstall opmanager

Hello, I'm using Manjaro Linux, I installed manageengine netflow analyzer, but now I can't uninstall it. It says in the manual that the folder for uninstalling the software is located at installation folder which is `/opt/ManageEngine/OpManager/_uninst`. The problem is that the _uninst folder doesn't exist. Please help me.
