QTP Error

[eroshan]

Hi all

I used this .vbs file to start my QTP test

Code:

Dim qtpApp    
   Dim qtpTest      
   Set qtpApp = CreateObject("QuickTest.Application")    
   qtpApp.Visible = true
   qtpApp.Open "C:\abc\Data", True  
   Set qtpTest = qtpApp.Test  
   qtpTest.Run
   qtpTest.Close
   qtpApp.quit
   Set qtTest = Nothing
   Set qtApp = Nothing

when i run it sometimes at the first time it generates a error.
(I attached error in snapshot) then i rerun the .vbs and it works well

What can be the reason ?

thanks
