share directory on windows

Hello,

I wanted to install text search dictionaries on Windows 8.4 installation with the following command:

CREATE TEXT SEARCH DICTIONARY skspell
      (template=ispell, dictfile = slovak_utf8, afffile=slovak_utf8, stopwords=slovak_utf8);

but got this error:
ERROR: could not open dictionary file "/usr/share/postgresql/8.4/tsearch_data/slovak_utf8.dict": No such file or
directory
SQL state: F0000

The file is located in c:\Program Files\PostgreSQL\8.4\share\tsearch_data\slovak_utf8.dict. Is this an incorrect
location?Where is the correct location or how to point the database to look in my current location? 

Thanks in advance,
Viliam
