Launching Mysql as Windows service with defaults-file On Vista

I am facing problem while lanuching MySql as Windows service on MS Vista ( Home and Ultimate) using --defaults-file option. Samething works fine under Windows XP. Here are steps :

1. I install MySql 5.1.39 with Typical option but don't configure the instance
2. I use Mysqld to launch server as Windows Service using
> Mysqld --install sname --defaults-file="C:\Program Files\MySQL\MySQL Server 5,1\sname.ini"

I get message as "Service successfull Installed"
3. I tried to start the service with " > NET START sname "
i get message "System error 1067 has occured"
4. If I check property of the service "sname" from Control Panel > Administrative Tools > Service , I find under "Path To Executable as :
"C:\Program Files\MySQL\MySQL Server 5,1\bin\mysqld" "C:\Program Files\MySQL\MySQL Server 5,1\sname.ini" sname

5. If i check the error log file of MySQL in Data folder, i get message as

C:\Program Files\MySQL\MySQL Server 5,1\bin\mysqld: Too many arguments ( first extra is 'C:\Program Files\MySQL\MySQL Server 5.1\sname.ini' )

If I omit --defaults-file option while installing service it works just fine. ( I made changes in my.ini to configure serivce as per my requirement, and copied at "C:\Program Files\MySQL\MySQL Server 5.1" before launching service.) If I check the property of that service it shows

"C:\Program Files\MySQL\MySQL Server 5,1\bin\mysqld" sname

On XP machine, the service launch with --defaults-file optoins result in service property

Path To Executable as :
"C:\Program Files\MySQL\MySQL Server 5,1\bin\mysqld" --defaults-file="C:\Program Files\MySQL\MySQL Server 5,1\sname.ini" sname

I have switched off UAC on Vista machine.
I don't find any solution for this problem. Please help me.
