API Mismatch error in Patch Manager


When you publish updates to the managed computers, an API Mismatch error displays in the SolarWinds Admin Console. 


  • SolarWinds Patch Manager is installed on a server running Microsoft® Windows Server® 2008 R2 server
  • Windows Server Update Services (WSUS) is installed on a separate server running Windows 2012 R2 Server


The WSUS server and the server hosting the Primary Application Server (PAS) are running different Windows Server operating system versions. 


Provision an Automation Server role on the PAS server. This server role bridges the gap between disparate WSUS API versions included with different Windows Server operating system versions.

  1. Locate the SolarWinds Patch Manager version running on the PAS.
  2. Download the identical SolarWinds Patch Manager version from the Customer Portal.
  3. Log in to the PAS server as an administrator.
  4. Run the SolarWinds Patch Manager installer and provision an Automation Server role.
    See the SolarWinds Patch Manager Installation Guide for instructions. 
  5. Create an Automation Server routing rule to prevent the API Mismatch error.
