How do you run it? Did you try to use cscript.exe or wscript.exe from c:\windows\SysWOW64\  or just wscript.exe <scriptname>.vbs or directly <scriptname>.vbs . In these cases the vbscript engine that interprets your script is located in c:\windows\system32 folder and it work in 64bit . But you should receive an error when you try to instanciate the object in the Set App = CreateObject("QuickTest.Application") instruction.

let us know. bye.

What are you running your VBS script through? Your script looks fine. But there might be a bit of a problem with the way it starts your file. Can you describe the steps of your operation? Please tell me in what way you store your scripts. And then how to start your script. 

Thanks
