MySQL Forums :: Install :: The service could not be started

Hi,

I am trying to install and execute MySQL in my computer, OS = Windows Vista.
I downloaded the .msi installation file, and I have done the whole configuration process with no problems but at the end, where I get the error "The service dould not be started".
I have been reading several information about this topic, and I saw some advice to execute the command

mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server 5.1\my.ini" --standalone --console

and the output I got is:

---------------------------------
Could not open required defaults file: C:\Program Files\MySQL Server 5.1\my.ini
Fatal error in defaults handling. Program aborted
090427 12:13:15 [Warning] Can't create test file C:\Program Files\MySQL\MySQL 5.
1.34\data\EV001E0B9DD24A.lower-test
090427 12:13:15 [Warning] Can't create test file C:\Program Files\MySQL\MySQL 5.

090427 12:13:16 InnoDB: Operating system error number 5 in a file operation.
InnoDB: The error means mysqld does not have the access rights to
InnoDB: the directory. It may also be you have created a subdirectory
InnoDB: of the same name as a data file.
InnoDB: File name .\ibdata1
InnoDB: File operation call: 'create'.
InnoDB: Cannot continue operation.
---------------------------------

But I don't understand exactly what does it mean. Maybe that it cannot get access to C: ??

Thanks,
