AddOn: Prevent from loading more than once

Question

Good Afternoon
Experts:
I appreciate you patience as I resurrect this topic since it has become an
increasing concern here.  We need a way to restrict our AddOn from "being in"
Task.mgr more than once.  We are working with Terminal Services.  A couple ways we have found more than one instance in TM is the User just opening another session or opening another session after a "problem/Issue/Crash". 
I have this code which restricts the AddOn from starting more than once here on my local machine:
Public Sub Main()
        Try
            Dim x As Integer = 0
            Dim Ctr As Integer = 0
            Dim som() As System.Diagnostics.Process
            som = System.Diagnostics.Process.GetProcesses
            Dim Name As String
            For x = 0 To som.Length - 1
                Name = som(x).ProcessName.ToUpper
                If som(x).ProcessName = "Test.Enhance" Then
                    Ctr += 1
                End If
            Next x
            If Ctr > 0 Then
                MsgBox("LBSI.Enhance AddOn is already started...Exiting application.", MsgBoxStyle.Critical)
                Exit Try
            Else
                ReInitializeAddOn()
                Application.Run()
            End If
        Catch ex As Exception
            HandleException("Main", ex, True)
        End Try
    End Sub
Is there a better more elegant way to do this? How about for Terminal Services?
Thanks in advance for your insight,
EJD
