I'm a beginner at OpenCV (still stuck at installing the libraries). I tried following this tutorial but got the error from VSC++ "Invalid License data. Reinstall is required" when compiling from cmake. reinstallation had no effect whatsoever.

Any help would be appreciated.

Your problem is with Visual Studio, not OpenCV. OpenCv, fortunately doe not require you to buy a licence. This is true for CMake too. Solve your problem with Visual Studio first.

Uninstall Visual C++ 2010.

Uninstall Visual C++ 2010 Isolated Shell

(... Uninstall every visual c++ 2010 related program in the add\remove programs list in the control panel, I had only these two, so I listed only these two above)

Reinstall Visual C++ 2010.
