Error "Fail to create empty document" occurs when I run my application run on a client PC, I was told that this is a licensing issue. Can any one tell me what is the license key and how I can get it? What should I pass when I call Create function??

I used the MSComm32.ocx and the code is

if(!m_commctrl.Create(NULL,0,CRect(0,0,0,0),this,ID_COMMCTRL))
{
TRACE0("Failed to create OLE Communication Control\n");
return -1;
}

If anyone of you know, please help me. Thank you.
