Cause

The VC++ 2012 re-distributable package is not installed properly because the package installation is blocked by an Antivirus software. This causes the Agent Management Business Layer plugin to crash during startup as it fails to load the SolarWinds.AMS.Proxy.dll.

Resolution

  1. Log in to the SolarWinds server as a Local Administrator.
  2. Check if all Visual C++ packages are installed in pairs (Both x86 and x64).
  3. Install the latest VC++ 2013 re-distributable (x86 or x64). For the installation steps, refer to Microsoft.
  4. Open SolarWinds Platform Service Manager from the SolarWinds Platform folder of the Start menu, and restart all services.
