Exception: System.Runtime.InteropServices.COMException: Class not registered

I have been using Powerbuilder 12.5 and I have migrate an old project from classic to .net recently. However there is an error regarding to my openwithparam() statement, each time I run the following code this exception occurred:

{System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Windows.Markup.XamlParseException: 'Initialization of 'AxMSCommLib.AxMSComm' threw an exception.' Line number '40' and line position '14'. ---> System.Runtime.InteropServices.COMException: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))
