Unsure of how to configure standalone .net processes

I have several windows services that I am trying to instrument, but cant seem to figure out how to. I have read the available documentation, but still not clear. All 13 windows services use the same .exe file, which I have defined in the config file. In the AppD UI, I all see a Machine Agent Tier(which isnt the name i want for the tier anyway), but nothing is being instrumented.

Here's what the config file looks like - what am i missing? How do I name the tier(in the UI) as SIKOMS Windows Service?

<?xml version="1.0" encoding="utf-8"?>
<appdynamics-agent xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <controller host="xxx" port="xxx" ssl="true" enable_tls12="true">
    <application name="SIKOMS" />
    <account name="xxx" password="xxx" />
    <proxy host="xxx="xxx" />
  </controller>
  <machine-agent />
  <app-agents>
    <IIS>
      <applications>
        <application path="/" site="Default Web Site">
          <tier name="" />
        </application>
      </applications>
    </IIS>
    <standalone-applications>
      <standalone-application executable="D:\sikoms\applications\SIKWindowsServices\SIKWindowsServices.exe" command-line="-x">
        <tier name="SIKOMS Windows Service" />
      </standalone-application>
    </standalone-applications>
  </app-agents>
</appdynamics-agent>

Any help would be greatly appreciated.
