Cannot create ActiveX component instance

[C# Programming]

End Google Ads 201810 - BS.net 01 --> I use axShockwaveFlash COM in the my frmSplash windows form for play flash file. I want to ShowDialog frmSplash in my main form. Its properly work. But I use thread I get error, Cannot create axShockwaveFlash component instance.

In my main form contain following code;

private void button1_Click(object sender, EventArgs e)
{
Control.CheckForIllegalCrossThreadCalls = false;
Thread thread = new Thread(DoSplash);
thread.IsBackground = true;
thread.Start();
}

private void DoSplash()
