Can you tell me when in the process of running the Exchange Tool (v2) the MsExTmzCfg.xml is created?

Q: can you tell me when in the process of running the Exchange Tool (v2) the MsExTmzCfg.xml is created? I want to run the tool from scratch again and I'm not sure if the xml came with the installation or if it was created later.
A: The MsExTmzCfg.xml file was created when you installed the tool
