Windows forms scalling

Question

I'm trying to avoid wrong form showing when "Scale and layout" in windows screen settings is different than 100%.
I've folloved this LINK, and it works but only in 2 cases
1 - in debugging mode in VS
2 - if i put my *.exe file together with *.manifest and *.config files in same location.
If *.exe is alone then it does not work. I'm looking for a clue what to do next.

Update
This is how application is run.

Private Sub Monitor_Click(sender As Object, e As EventArgs)    
    Dim trd As New Thread(AddressOf ShowMonitor)
    trd.SetApartmentState(Threading.ApartmentState.STA)
    trd.Start()
End Sub

Private Sub ShowMonitor()
    Dim frMonitor As System.Reflection.Assembly = System.Reflection.Assembly.Load(File.ReadAllBytes("path to folder with DLL files\Monitor.dll"))
    Dim oType As System.Type
    Dim pControl As System.Object

    oType = frMonitor.GetType("Monitor.frmMonitor")
    pControl = Activator.CreateInstance(oType)
    Application.Run(pControl)
End Sub

So my "monitor" application works as expected only in 2 cases written above.
