In the applications, put a file named

App_Data/CommandLineOverride.xml

This file - if found - will be read as xml and used as parameters.

Example of valid input:

<root>
  <arg>port=5020</arg>
  <arg>nohttps</arg>
  <arg>host=localhost</arg>
  <arg>iis=https://localhost/TKDebug</arg> // probably the only param you send for IIS hosting 
</root>

The file is practical since it will enable you to just unzip a fresh version of the server software into the old location. This will will stay untouched - and the server is ready to start with these settings.
