flash control through windows forms application does not work any more after explorer update of 26th of december 2015

Question

We have an windows form application that shows flash content. Until saterday 26th of december 2015 this worked perfectly.

now I get: A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in AxShockwaveFlashObjects.dll Additional information: The data necessary to complete this operation is not yet available. (Exception from HRESULT: 0x8000000A)

When I try to ask the TotalFrames from the control after loading. Did anybody experienced the same?

Windows Forms Code (visual studio 2015):

Private WithEvents FlashControl As AxShockwaveFlashObjects.AxShockwaveFlash = Nothing

Private Sub Form1_VisibleChanged(sender As Object, e As EventArgs) Handles Me.VisibleChanged On Error Resume Next

FlashControl = New AxShockwaveFlashObjects.AxShockwaveFlash
FlashControl.Name = System.Guid.NewGuid.ToString
FlashControl.Size = New System.Drawing.Size(500, 300)
Me.Controls.Add(FlashControl)
FlashControl.CreateControl()

If FlashControl.Created Then
  FlashControl.LoadMovie(0, "C:\ProgramData\PADS\Content\nds1011_contentorganizer\General-testfiles\studenthealthpack.swf")
  System.Threading.Thread.Sleep(2000)
  Dim GetTotalFrames As Long = 0
  If FlashControl.TotalFrames <> 0 Then
    GetTotalFrames = FlashControl.TotalFrames
  Else
    GetTotalFrames = 0
  End If
  FlashControl.Play()
End If

End Sub

Found this at another website:

First, you will go to Project>>Properties>>Linker>>System, in the field "SubSystem" you choose "Windows (/SUBSYSTEM:WINDOWS)", click Apply. Then go to Project>>Properties>>Linker>>Advanced, in the field "entry point", input value "Main" and Apply, finally click OK. After, you go go file code of form you created(ex: MyForm.cpp) and input code below to this file

using namespace System;

using namespace System::Windows::Forms;

[STAThreadAttribute]

void Main(array<String^>^ args)

{

Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);
Project1::MyForm form; Application::Run(%form);

}

Save and exit visual studio, and then open it again, UI Form will work.
