Call word doc using VB 3.0

I am trying to create word document using VB 3.0.

I need to create word doc at run time & insert & format text at run time.

My machine is NT 4.0 workstation.

I tried following code

Dim Myobject As object
Set Myobject = CreateObject("Wordproc.Document")

>> I am getting error on the above line
   "OLE Automation Server can not create Object"

Myobject.bold
Myobject.insert "Hello World"
Myobject.Print
Myobject.saveas "c:\neeraj\winfax\runtimedoc.doc"
 Myobject.bold

Please Help
