Overview

The following error is received when installing NCM on additional poller server:

 

Solarwinds NCM cannot be installed on this machine due to an incompatibility with one or more currently installed Solarwinds product versions.

Environment

NCM, all supported versions

 

Note: If you are running Orion Platform 2017.3 MSP4 and later, you can use the Orion Installer to install scalability engines (Additional Polling Engines, Additional Web Servers, and High Availability backup servers).

Cause 

You are using a full version of NCM instead of using the correct NCM Additional poller installer.

Resolution

  1. Download the installer from the Customer Portal site https://customerportal.solarwinds.com/Downloads.
    Note: There is an individual installer for NCM Additional Polling Engine.
  2. Under Individual Downloads section, download the correct version of the Orion Network Configuration Manager(NCM) Additional Polling Engine.
  3. Install the NCM Additional Polling Engine installer manually on the additional poller.

    Note: If you have a lower version of NPM module, upgrade it first to version 11.5.2 before upgrading to NCM 7.4.
