TestComplete stops working when execute CreateObject("Excel.Application")

Hi, 



The TestComplete stops working when execute the following code:



Dim objExcel

Set objExcel = CreateObject("Excel.Application") 



TestComplete just stops working and does not have respond. I tried to click the button Stop, but it does not take effect.



I have been using the above snippet for a couple of months, and it works in majority of cases. During the months, I encountered the issue twice. The issue could be solved if I reboot the machine.



Any suggestions will be quite apprecriated.



Cheers.
