I'm trying to install the McAfee NSM IPS extension (188.8.131.52) for ePO 4.6 and upon uploading the .zip file into the Extensions, I get this error:
Unable to install extension. java.lang.Illegal.State.Exception: A web app is already deployed at context /ISExtension.
I see no extensions for NSM in the Extensions directory in the ePolicy Orchestrator installtion directory nor do I see it listed within the installed extensions listing on the ePO 4.6 server to remove it.
Any ideas on how to get this extension installed and/or get around this error?
