@Chris, don't worry about it. I just tried it on another Win7HP x64 machine and it worked OK, so put it down to just mine requiring a reinstall
But on the off chance, how are you detecting the presence of the webcam, (maybe I have something leftover on my system)?
A little later ... more testing, I just remembered my netbook, (win8 Pro x86), has a webcam
The netbook hasn't suffered the same OS abuse I've put my desktop through, so it's results should be better - the webcam is enabled and has drivers and is shown working in Device Manager ... however ...
When I ran Cameo I had a window open, (title: Video Source), asking which Capture Source I wanted, there's only the one so I selected it and hit OK. The icon showed that no
webcam was connected and when I used Check Status, it also said no webcam was connected.
Ten seconds later. the Video Source selection window opens again and prompts me to choose another video source - so I select the webcam again. This time the icon/Check Status says a webcam is connected.
Ten seconds later, Video Source window opens, I select it again and this time it says it's not connected.
And it continues to say it isn't connected, however every ten seconds or any time I use Check Status it asks for the Video Source to use.
