Installing SQL Server Express 2005 June CTP from command line

I am trying to install SQL Server Express 2005 June CTP from command line, but by having the BIN folder completely blank.
Can anyone please specify the command line options, which I can use while installing, which can install it silently ?
Plz. write the entire statement to be written at the command prompt.
Thanking in advance.

I believe

SQLExpre32.exe -q /norebootchk /qn reboot=ReallySuppress addlocal=all instancename=SQLEXPRESS

will do the trick.
