Failed to download or run the Scalability Engine installer from the main server

Updated September 20, 2017



The Scalability Engine installer for Additional Polling Engines, Additional Websites, and High Availability backup servers could not be downloaded from the main Orion server or times out when run.


Products running Orion Platform 2017.3, such as:

  • NPM 12.2
  • NCM 7.7


After trying to download the installer three times, the download will fail. 



  1. Log on to your main Orion server, and navigate to ProgramData/SolarWinds/Installers/CoreInstaller.msi.
  2. Rename the file to CORE_xxxx.x.msi and copy it to a folder named CORE_xxxx.x.xxxx on the other computer. Use the name of the Core_xxxx.x.xxxx ZIP file in /SolarWinds/Installers as the folder name.
    For example, if the ZIP file was named Core_2017.1.5300.ZIP, name the folder CORE_2017.3.5300\ and the file CORE_2017.3.MSI.
  3. Download the Scalability Engines installer from the Customer Portal.
  4. Run the Scalability Engines installer on the other computer.
  5. Immediately copy the CORE_xxxx.x.xxxx folder to %temp%\SWOrionSetup[currenttimestamp]\subinstallers\.
    For example, if the ZIP file was named Core_2017.1.5300, copy the file to %temp%\SWOrionSetup[currenttimestamp]\subinstallers\CORE_2017.3.5300\.
  6. If you have applied an Orion Platform hotfix, copy the MSP file from the main server to %temp%\SWOrionSetup[currenttimestamp]\subinstallers\ folder on the other server.

The Scalability Engine completes successfully.


If the above steps don't resolve the issue, you can try the steps below to make this work in environments with more than 1 Additional Polling Engine where the install completes successfully on at least 1 of the Additional Polling Engines:

  1. On the Additional Polling Engine that fails when downloading the packages, run the Scalability Engine Installer, but don't go through the installation yet.
  2. Log on to the Additional Polling Engine where the Scalability Engine Installer completed successfully and navigate to C:\ProgramData\SolarWinds\Installers.
  3. Copy and paste the entire contents of the Installers folder from the working Additional Polling Engine over to the to the "%Temp%\SWOrionSetup[currenttimestamp]\Subinstallers" directory on the Additional Polling Engine that is having the issues with the installer.
  4. Once the files have been copied over, continue with the installation of the Scalability Engine Installer on the Additional Polling Engine with the problem.

The Scalability Engine completes successfully
