[RESOLVED] [2008] Preventing form from loading unless specific file exists

[cmmorris1]

How can I prevent my form from running unless a specific file is on
the users pc? I need to make sure it's my software and not any exe
with the same name? Perhaps a md5 hash check or something? So far
this is all I have but want to have a better check or prevent the software
from running.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If My.Computer.FileSystem.FileExists("C:\Program Files\XYZ\xyz.exe") Then
            Me.Show()
        Else
            MsgBox("You Need To Install XYZ To Continue")
            Application.Exit()
        End If
    End Sub
