Exchange 2010 SP3 Upgrade failed due to ‘MonAgentCore’


I deploy Exchange 2010 on Azure. When i try to upgrade Exchange 2010 to Exchnage 2010 SP3, it’s failed.

Error: Setup can’t continue with the upgrade because the ‘MonAgentCore’ Process {} (ID:6052) has open files. Close the process, and then restart Setup.



To resolve this issue, you need to kill MonAgentCore Service Then restart upgrade. To do that, you need to follow below steps:

  1. Open “c:\packages\plugins\Microsoft.Azure.Diagnostics.IaaSDiagnostics\\Monitor\x64”, Rename MonAgentCore to MonAgentCore1 and MonAgentHost to MonAgentHost1


  1. Open Task Manager, Kill MonAgentcore and MonAgentHost


  1. Then Try to rerun upgrade now, it should be run successfully
