Issue/Introduction

While running the Management Server Configuration Wizard (MSCW) an error message is presented saying "The process launcher port is used by another application. You must specify a different port". 

Note: The SEPM service specified in this message may be different, however, the solution will be the same.

Environment

Release :

Cause

It is not uncommon for an application to connect to a currently unused port resulting in a block when trying to assign a second service to the same port. Such as when SEPM services have been stopped during an upgrade.

Resolution

Open a cmd prompt and type netstat -ano | findstr [port number]. This will reveal the application that is currently using the port.

Temporarily stop that application to free up the port, continue completing the MSCW, then restart the application.
