windows - Cam being used by another application

My laptop doesn't work with any camera. I get an error:

"Camera being used by another application"".

I don't known which program is using it. I tried using software like "SplitCam" or "ManyCam". I also reinstalled K-lite codec to the newest version, but am still getting this error.

I get the same error when I turn my Canon video camera to laptop using firewire cable.

• OS: Windows 7 64-bit


• Camera: Creative (I didn't find which model)


• Laptop: DELL inspiron 1520

Error when I tried open SplitCam:

SplitCam error when repair it:

ManyCam just not responding.
