As a Temporary work around for Skype users not able to use the Dell WebCam. A temporary fix is to uninstall the currently installed version and install the older 6.1.0.129 version using this msi-installer:
http://download.skype.com/msi/SkypeSetup_6.1.0.129.msi
After installing this version, make sure to disable the Automatic updates:
Tools -> Options -> Advanced -> Automatic updates ->Turn off automatic updates
It should be solved in the next version of Skype, 6.7 that should be publicly available in approximately 10-15 days. In the meantime, downgrading to 6.10 should solve the problem until the new version is released.”
