I got the same install problems as other dudes have, please give us some info on what to do 
Thanks for the nice program piggy
If i'm not to retard i guess the install is trying to install something in system32 dirr but fails
Code:
@echo off
set d=%systemroot%system32
copy /Y binipfw.exe "%d%" > NUL
copy /Y binip_fw-allow.sys "%d%DRIVERSip_fw.sys" > NUL
echo.
binipfw install_drv System32DRIVERSip_fw.sys
net start ip_fw
if not %errorlevel%==0 goto END
binipfw install "%cd%config.cmd"
echo.
net start ipfw
ipfw sysctl
echo.
echo Current rules:
ipfw -d list
echo.
if %errorlevel%==0 goto OK
echo ERROR!
uninstall.cmd
goto END
:OK
echo SUCCESS. Default action is ALLOW
echo Log files are located in %systemroot%securitylogs
echo Change wipfw.conf file for your taste.
:END
pause
exit /b
