I installed Microsoft Expression Encoder  4 Screen capture SP2 pro. And I get this error when trying to setup my cam "Unable to create Device HD Webcam. It may be in use or not functioning".

The cam is not being used by another app

It is fully functioning with all other apps

Screen Capture version 4.0.4276.0

Tried all versions of the screen capture got the same results

Installed uninstalled, updated drivers same problem

Any suggestions, thanks
