I don't have a webcam, and VH Multi camera studio is screen capture software i use. Everytime i open skype, or on startup, it opens a fullscreen window of VHMCS. I have gone through the settings trying to disable the webcam (or find whatever thinks this is my webcam) with no luck, my only option under Options -> Video Settings is "Automatically recieve call and video sharing from...".
I want to stop skype from opening this software on launch, any help will be appreciated.
You must be looking at some wrong place. The option "Automatically receive call and video sharing from..." is under Tools -> Options -> Privacy settings -> Show advanced options. If you go to Tools ->Options -> Video settings, then you should see what Skype is using as your video capture device. Anywhere, your problem is that whenever there is no webcam installed, Skype will make use of any other capture device installed on your computer and there is no option in Skype to stop this. However, there is an un-documented “fix” which you can try but without any guaranty that it will work.

Insert there these lines:
