My skype software not shown the vedio, however, cam installed with cd. the skype shows message that cam not open rendered.

when it shows at device manager it mean the driver for the webcam has been installed successfully , but u dont have any software installed to view ur webcam u need to install the software which every webcam vendor has provided. or if u r using yahoo, hotmail , skype tehn simply start vedio conference it will work fine.

I believe Skype requires at least DirectX 11 to work now.

Visit the Logitech website and browse the photo gallery for your model and click on the photo to navigate to the support page.
Note - Older models on page 2 - look for the link at the bottom right of page 1 and click on it "Still can't find your product?"

In addition to the Logitech installer you will need to check the support software - Microsoft DirectX . This comes pre-loaded on most Windows computers but has to be updated - I am currently on version 11
To start the DirectX Diagnostic Tool, click 'Start', click 'Run', type dxdiag in the Open box, and then click OK
Run through the tabs checking the 'notes' windows for information
The version will be shown on the 'Systems' tab

Procedure to re-install Logitech software
Close all programs while uninstalling - downloading and uploading software
Disconnect your webcam
Uninstall the current webcam software on your computer
Restart computer
Download the Installation package from Logitech
Run the installer and choose your options during the installation - You may not want Logitech Chat but the Desktop icon for the webcam toolbar is a must.
Connect your webcam when prompted.

Its good practice to disconnect and re-connect your webcam before you start (To reboot the webcam software) - if you have been using it elsewhere the SKYPE software may have difficulty in locating it, even if you exited the previous program correctly.
The reason being, the webcam software can remain hooked-up to a program and needs to be rebooted.
Mine, I just unplug it from the USB and plug it back in to reboot the software.

Before opening Skype disconnect your webcam for a couple of seconds - if its inbuilt restart your computer or disable / enable it from the Imaging folder in the device manager and do not open your cam for a preview but wait and let the Skype software take full control when you start a video chat.

it is quite possible that the webcam is being used by other application like msn messgenger or yahoo messenger .. try closing them and then use skype. also try unplugging the cam...restart the system and then plug the cam once again.

Till you install its drivers from the CD that came with it, it will not show up anywhere. Install the CD withoutconnecting the cam. After installation of drivers only will the ca be recognised by both Windows and Skype.

Open Skype, Tools, Options, Calls, Video Settings,
