Hello, i've been working with this issue for more than a week now. Have tried all the solutions on the net without any success.

Windows 7 home premium x64 is installed on the machine. When trying to use any application using camera shows up a message, that webcam is used by another application. This pops up on Skype and Dell Webcamcentral. Ms Silverlight shows black screen, no message.

Mar 3, 2018 - How To Install Mac Os X On Dell Xps L502x. As about two years ago, when I was trying to install SL or Lion as a Hackintosh on my XPS.

The device is present under imaging devices in device manager. The driver installed is Microsoft 6/21/2006 ver. 6.1.7601.18208, status 'device is working properly'. Driver files: ksthunk.sys, usbvideo.sys and ctclsflt.sys after installing webcam central. Here is what i tried: 1.

Installing drivers from Dell.com in the correct order 2. Uninstalling webcam driver and letting windows install the driver from windows update.

Uninstalling windows driver and installing Quanta webcam driver before restart. Note, that in all 3 steps quanta driver never showed up in driver details in device manager.

Uninstalled Webcamcentral, downloaded and installed ver 6.1 Skype.

Aspen plus manual. Started windows in a clean boot state. Installed process observer. Webcam is used only by skype, but skype gives 'camera used by another app' error message.

Turned off laptop, removed ac power and battery, pressed power on button for 30 secs. Tried to update driver through device manager - driver is up to date. Reinstalled windows and installed chipset drivers + wireless drivers and let the windows update.

Then installed all Dells drivers in the correct order. Restored to the point before windows update and installed Dell drivers in the correct order. Restored to the point after windows update again.

Installed ms Silverlight, camera shows black screen. Room is light, tried a sheet of white paper close to the camera.

Tried different skype versions again, uninstalled skype. Process observer shows that nothing uses webcam. Supportassist shows failure in webcam at all checkup stages. Supportassist suggests to turn of programs that might be using camera. Tried all the steps before windows reinstall. I gave up and ask for your help. Here is Supportassist diagnostics log.
