Working with ThinApp QTP

Hi, We are using ThinApp QTP 11 Application on windows 7 OS. Can any one help me with the below scenario: I am trying to invoke the QTP using commandline, for this I prepated a VB Script which creates QTP Object and executes my test suite.

Set qtpApp = CreateObject(“QuickTest.Application

qtpApp.Launch

qtpApp.Visible = True

But when I execute this scipt, I am getting “ActiveX Component can’t create an object:” error message.

Please note that I am able to create excel, word objects. I feel this might be an issue with QTP application as it is ThinApp.

Can some one help me out in this regard.
