executing .msi file

I am trying to run an .msi file using the following command.

start /wait msiexec.exe /qb /i $PLUGINSDIR\mysql_odbc.msi

But this gives me compile error "Invalid Command : start". Any idea what is wrong with the command.

try: ExecWait 'msiexec.exe /qb /i "$PLUGINSDIR\mysql_odbc.msi"'

if you want to use start, you must prefix the command with cmd.exe or command.com (depending on the OS, you can read the COMSPEC env. variable if needed) on Win9x, start is a single .exe, on NT it is a built-in command in cmd.exe

Thanks Very Much,
