I started feeling suspicious about the environment, so I got a friend who had OpenCV all set up to try out my code and he could run it with no problem... So I reinstalled everything, but this time I chose Microsoft Visual Studio 2010 SP1 and OpenCV 2.4.3, and it worked correctly. If someone is having the same problem, I recommend downgrading to VS2010. Also, this video installation guide [this video] was really helpful when I was setting the environment! Thank you :)

Hey there I followed the installation guide of OpenCV 2.4.4 on Windows 7 here [this video] And I linked all system path variables to their respective directories. I also followed all his steps of including the libraries in the linker and C/C++ properties, but I used vc11 instead of vc10 (he's using opencv 2.4.3). And I was able to build the project just fine, it knows where the libraries are. But once I run it a window pops up with the following error message "opencv_core244d.dll is missing from your computer". It can't seem to find the .dll files even though I'm pointing to the right directories. Any suggestions? EDIT: I read online that this sort of thing can happen if the .dll files are not in

I would suggest that you check to make sure your directories and environmental variables are entered correctly. Then try manually retyping the libraries in the linker, carefully making sure you entered it correctly. Check in your 'lib' folder ( C:\opencv\build\x64\vc10\lib ) to make sure you put the right file name in your additional libraries. For example, you could have file opencv_ffmpeg231.lib from version 2.3.1. This may have been the case during the making of the tutorial but change the number to your current version. i.e, for version 2.4.7 it would be *opencv_ffmpeg247.lib* just check your "lib' folder to make sure they're the same name Also, Try this youtube Tutorial for installing O

I found the solution on this video tutorial: [this video] I have installed VS2012 before and I installed VS2010. They work fine together. Then I followed the steps on tutorial and it works fine now. Note: I installed opencv version 2.4.3.
