Mysql without install?

[Fooz]

ok, so i made a login for a program I wrote. The program was written in vb 2008 express edition. It uses a MySql connector to connect to a database and confirm the username and password.

Here's the source:

Imports System.Data.SqlClient
Imports MySql.Data.MySqlClient
Public Class Login
    Dim mysqlconnection As MySqlConnection

    Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click

  'Retrieves online database
  TextBox1.Text = "Status: Verifiying"
  mysqlconnection = New MySqlConnection
  mysqlconnection.ConnectionString="server=db4free.net;Port=3306; user id=<username>; password=<password>; database=<database>"
  mysqlconnection.Open()

  Dim myadapter As New MySqlDataAdapter
  Dim sqlquary = "SELECT * From Users WHERE Username='" & UsernameTextBox.Text & "' AND Password='" & PasswordTextBox.Text & "';"
  Dim command As New MySqlCommand
  command.Connection = mysqlconnection
  command.CommandText = sqlquary
  myadapter.SelectCommand = command
  Dim mydata As MySqlDataReader
  mydata = command.ExecuteReader

  'Verification
  If mydata.HasRows = 0 Then
    MsgBox("Incorrect Login: Access Denied", MsgBoxStyle.Critical, "Access Denied")
    UsernameTextBox.Text = ""
    PasswordTextBox.Text = ""
    TextBox1.Text = "Status: Failed"
  Else
    MsgBox("Successful Login: Access Granted", vbInformation, "Access Granted")
    Form1.Show()
    Me.Close()
  End If
    End Sub

    Private Sub Cancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Cancel.Click
  Me.Close()
    End Sub
    Private Sub Passwordtextbox_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles PasswordTextBox.KeyPress

  'Prevents sql injection
  If e.KeyChar = "=" Then
    MsgBox("Error: sql Injection detected, shutting down.", MsgBoxStyle.Critical, "Hacker Detected!")
    End
  ElseIf e.KeyChar = "-" Then
    MsgBox("Error: sql Injection detected, shutting down.", MsgBoxStyle.Critical, "Hacker Detected!")
    End
  ElseIf e.KeyChar = "'" Then
    MsgBox("Error: sql Injection detected, shutting down.", MsgBoxStyle.Critical, "Hacker Detected!")
    End
  Else
  End If
    End Sub
End Class

Here's the problem, it works fine on mine, but whenever it's given to someone that doesn't have the mysql connector installed, it won't run correctly, and crashes. I've tried just updating the clients .net framework, but it simply won't work. Is there any way I can make my code so it will still be compatible with computers without the mysql connector? If not, then are there any alternative methods to achieving an online login(with a link please)?
