This is very easy and it would definitely be valuable under Win env.
Please add a an environment variable for the VLC folder path. It just seems this would be logical during install of VLC.
Would make the life of programmers much easier and would keep from having to do some kind of scan to verify if EU has installed VLC.
I don't mess around in C/C++ much, but I would gladly figure it out if this is the only way to get it done.
BTW, this can probably be done in the installer. I'm sure I don't have to tell you this though...
