OpenCV 2.4 install problem

edit

Hey Guys

I have a problem, i had opencv 2.2 which was easy to install and when i try to run a program for camera capture, but a problem occurred that only a grey output window was displayed. So i thought i would upgrade it to 2.4. So i downloaded 2.4, which told me to extract to a place, i extracted it to C:\OpenCV2.4\

I went to link this to Visual studio 2010 but when i try to link libraries, i couldn't find lib folder in the opencv2.4 folder. I forgot to mention since inside opencv2.4 was a folder called opencv i moved everything in there outside and delete the opencv folder.

Help would be appreciated either on fixing the camera or help with installing opencv2.4 as the lib folder is missing

thanks
