An Error By Using Ncbi-Blast-2.2.25+ (On Windows)

Hi all I downloaded blast+ software package (for windows), and installed like theBookshelf; to run it i used this

"ncbi-blast-2.2.25+/bin/blastn –query text_query.txt –db refseq_genomic –out output.txt"

but it didn't work and gave me an error:

"DESCRIPTION
   Nucleotide-Nucleotide BLAST 2.2.25+

Use '-help' to print detailed descriptions of command line arguments

========================================================================

Error: (106.18)

NCBI C++ Exception:

 Error: (CArgException::eSynopsis) Too many positional arguments (1),
the offending value: ûquery

 Error: (CArgException::eSynopsis) Application's initialization failed"

I couldn't what is my mistake. if possible help me (with more details please, because i am a bit freshman about bioinformatics). i really need it. thanks a lot in advance.

regards
