I have same issue. I just got this new XPS15 laptop with quantra integrated webcam. Dell webcam software was working fine, but in an effort to remove all clutter, I uninstalled that (among many other preloaded software). So, then I want to record video and redownloaded it because resource CD has the webcam driver, which works just fine and which is also automatically downloaded by windows update (clean auto-install), BUT IT does NOT have the dell webcam software. I downloaded the dell webcam software from the website; however, unlike before, I get an error message saying "no supported webcam driver." Apparently, this software, version 2.01.26, is NOT the same as the version that comes preloaded on your laptop! Buyer beware, if you uninstall your dell webcam software, you will never be able to use it again, because the web version does not work with your dell laptop. Because the webcam driver works independently from the webcam software, you can still freely use applications like gmail video chat. To know definitively whether you are screwed, with the dell webcam software open, click on settings and navigate to motion detection. By clicking the "detection" entry on the left field, you will see a box appear on the right field that will show a working webcam field of live video capture (and below it is a slider used to set detection threshold). Because you can see yourself in this setting, you know the driver works, but because you cannot use the software to capture footage, you know the software is incompatible with your dell xps15 laptop. If someone has the factory-installed version of this software, which is again not available on the CD, please be so kind as to upload it for us all to download to restore functionality to our XPS15 laptops.
