Center Message In Msgbox

How can I get the message to display in the center of the display box?

If i < 3 Then If MsgBox(Tries - i & " Tries Remaining." & vbLf & vbLf & " Try Again?", vbYesNo) = vbNo Then Exit For

As you can see the "try again?" & the text "Tries Remaining"works fine by entering spaces, but the number that is suppose to display with "Tries Remaining" does NOT center. How can I get the number to display in the center along with the text?

This is the complete code.

Private Sub Workbook_Open()
Dim i As Integer, Tries As Integer
Dim PassTry As String
Const Pass As String = "Password"
Dim storedPath As String
On Error Resume Next
storedPath = ThisWorkbook.CustomDocumentProperties("PathCertString").Value
On Error GoTo 0..................
