Record Video won't use USB Webcam

Hello,

I am using Adobe Presenter 9/PowerPoint 2013 (32 bit) on a Windows 7 machine.

I am trying to use the Record Video function of Presenter, however, I can't seen to use an external USB webcam.

Steps.

1. I click Settings

2, I choose USB 2.0 PC Cam

3. I click OK

4. I get a message on the recording screen that the camera is turned off

(I attempt to click the picture of the camera to turn it on, nothing happens)

5. I go back into settings and the Selected camera is reset to None.

I know the camera works as I can use it in other applications.

Any help would be appreciated
