Answer : This can be configured both by command-line ( nltk.download(..., download_dir=) or by GUI. Bizarrely nltk seems to totally ignore its own environment variable NLTK_DATA and default its download directories to a standard set of five paths, regardless whether NLTK_DATA is defined and where it points, and regardless whether nltk's five default dirs even exist on the machine or architecture(!). Some of that is documented in Installing NLTK Data, although it's incomplete and kinda buried; reproduced below with much clearer formatting: Command line installation The downloader will search for an existing nltk_data directory to install NLTK data. If one does not exist it will attempt to create one in a central location (when using an administrator account) or otherwise in the user’s filespace. If necessary, run the download command from an administrator account, or using sudo. The recommended system location is: C:\nltk_data (Windows) ; ...

Answer : There are several possibilities. To list the two most frequent ones: c:\full\path\to\gswin32c.exe should always work. For 64bit systems, use c:\full\path\to\gswin64c.exe . After a fresh installation using a standard windows installer, you may need to reboot before the updated %path% environment variable is used. Open a cmd window and (assuming your Ghostscript installation ended up in c:\path\to\gs ...) then type set path=c:\path\to\gs\gs9.02\bin;%path% . From this same cmd window you can now simply use gswin32c to start Ghostscript (use gswin64c on 64 bit Windows)...
