Cannot install SRM polling engine due to compatibility errors

Updated March 15, 2017


Cannot install standalone SRM polling engine on a server without an additional polling engine. During installation, you get the following error:

The version of Orion Core installed on your primary Orion server is never than the version of Orion Core that you are trying to install on your additional server.

As for this case, SRM 6.3 is installed on the main poller and is attempting to install 6.3 on the additional polling engine.


  • SRM 6.3.0
  • NPM 12.0.1
  • SAM 6.2.4
  • Orion Platform 2016.2.100


Core has been upgraded on the main poller beyond 2016.1. SRM 6.3 was shipped with Core 2016.1. When ran on the main server, the installer skipped Core installation as it was already on a later version (one of the products upgraded Core to 2016.2). However, on the additional poller Core was not present so the installer tried to install 2016.1.


  1. Go to C:\ProgramData\Solarwinds\Installers on the main Orion server and copy the CoreInstaller.msi file.
  2. Transfer the copied file to the additional poller server (C:\ProgramData\Solarwinds\Installers). Create the folder if it does not exist.
  3. Run the CoreInstaller.msi and install Core using the CoreInstaller.msi ORIONINSTALLATIONTYPE=POLLER command.
  4. Rerun the SRM 6.3 installer.
