chcp 65001 >NUL
::
::
if "%1"=="" goto par_mis
if "%2"=="" goto par_mis
if "%3"=="" goto par_mis
under Win7 work fine,microsoft office 2007 Pro Plus activation, but under Windows2003 batch unexpectedly finish
after line:
chcp 65001 >NUL
No error message,windows 7 professional 32bit key, %errorlevel% is 0
