Hello Dojo,

I have a Cluster of 4 agents where I am unable to install NATS on 2 of them and therefore the DataMiner won't start up.
When I try to install the NATS, I receive the following message saying the installation failed on one of the prerequisites.

Where I can find which prerequisites are failing?

DM version: 10.2.4
OS: Windows Server 2012 R2

Hi Pedro,

Is it possible this is on a Windows Server 2012 server? (Not Server 2012 R2) I think NATS is only supported from Server 2012 R2 onwards.

Hello Jens,

All the agents on the Cluster are running Windows Server 2012 R2 and I can’t install NATS on 2 of them.

Hi Pedro,
Could you check the PowerShell version running on that server?
Could it be the case that you are running a version older than 5?
You can check the version by opening a PowerShell command line and run:
$PSVersionTable

The last command executed returned the exit code “-1”, this means that something went wrong.

You can try to run that command manually and see if nssm.exe itself returns a more human friendly error message?
