Windows 7 driver for Software Defined Radio Receiver USB Stick - RTL2832 w/R820T

I have just purchased an SDR device - Software Defined Radio Receiver USB Stick - RTL2832 w/R820T
I have downloaded SDR-Sharp for windows from a link on the supplier's (Adafruit) web site SDR
The SDR-Sharp software includes a batch file which is to be run to install the required device driver.
Running the batch file however in a windows 7 Professional 64 bit system does not do anything.
I have tried running the command "httpget http://osmocom.org/attachments/download/2242/RelWithDebInfo.zip tmp\RelWithDebInfo.zip
" in a command box but get the error "httpget is not an recognised internal or external command".

Can someone advise me as to from where the windows 7 driver can be downloaded ?

The batch file content is as follows:

@echo off

mkdir tmp

echo Downloading RTLSDR Driver
httpget http://osmocom.org/attachments/download/2242/RelWithDebInfo.zip tmp\RelWithDebInfo.zip

echo Downloading Zadig
set zadig_exe=zadig.exe
ver | findstr /l "5.1." > NUL
if %errorlevel% equ 0 set zadig_exe=zadig_xp.exe
httpget http://zadig.akeo.ie/downloads/%zadig_exe% %zadig_exe%

unzip -o tmp\RelWithDebInfo.zip -d tmp
move tmp\rtl-sdr-release\x32\rtlsdr.dll .

rmdir tmp /S /Q
