I have succesfully worked with pythonXY of older version with the package 
netCDF. But after installing latest update, it doesnot work any longer. I tried 
installing it on two different machines (Windows Vista, Windows 7), I tried 
updating netcdf4 library (from unidata official webpage) and after reinstalling 
pythonXY 2.7.10, it didnot help. As I understand the problem is in loading 
pre-compiled module namely "C:\Python27\lib\site-packages\netCDF4\_netCDF4.pyd"
