The error reads as below:

Traceback (most recent call last):
File "C:\Anaconda2\Lib\_nsis.py", line 164, in <module> main()
File "C:\Anaconda2\Lib\_nsis.py", line 150, in main
  mk_menus(remove=False)
File "C:\Anaconda2\Lib\_nsis.py", line 94, in mk_menus
  err("Traceback:\n%s\n" % traceback.format_exc(20))
IOError: [Errno 9] Bad file descriptor

And the solution is:

Go to C:\Anaconda2\Lib (default path for Anaconda Lib installation) and type

..\python _nsis.py mkmenus
