I just used the pyFLTK installer (http://sourceforge.net/projects/pyfltk/). That gave me the DLL load error.
I read that you have to install FLTK as well. Where exactly do I install this?
As well, after reading this question, I found out that _fltk.pyd was apparently missing LIBGCC_S_DW2-1.DLL, LIBSTDC++-6.DLL, MSVCR71.DLL, GPSVC.DLL. How do I fix this?
