Quality Center 11 AxControl Error

In Quality Center 11 when I double click on an automated test in Testlab and then choose “Execution Settings” on the left and click on the “Automated” tab I get the following error:

“Unable to get the window handle for the ‘AxControl’ control. Windowless ActiveX controls are not supported.”

The solution turns out to be to turn off DEP for the machine that you're running Quality Center on.

On the command line, type: bcdedit /set {current} nx AlwaysOff

You'll then need to reboot the machine.

To turn DEP back on, use the command : bcdedit /set {current} nx AlwaysOn


  1. I am accessing Remote machine and on that machine i am facing this issue.I have executed this command and restarted remote machine. Still I am getting the error.
