How can I stop the initial auto-discovery process



I am new to PRTG and am currently interested in testing out the free version of the Network Monitor. I am concerned with the initial auto-discovery causing performance issues on our network so I have shut down the VM it is running on. Is there a way to disable the initial auto-discovery in the newest version ( in order to avoid any potential issues this process may cause? It doesn't seem like that is a good idea for new installations, as it may not be desirable for all users/networks. I appreciate any assistance.

Hello there,

In order to avoid the initial auto-discovery that is being performed on a fresh install, run the installer in command prompt and add /NoInitialAutoDisco=1 as parameter.
