Starting MySQL as a service (no replies)

I have just installed MySQL Installer package for Windows.
I am trying to start it as a service.
I am getting errors when I do this.
mysql -u root -p install
Gives me
Plugin 'FEDERATED' is disabled.
The InnoDB memory heap is disabled
*Mutexes and rw-locks use Windows interlocked functions
Compressed tables use zlib 1.2.3
Operating system error number 5 in a file operation
The error means mysqld does nto have the access rights to the directory. It may also be you have created a subdirectory of the same name as a data file.
File name .\ibdata1
File operation call: 'create'.
Cannot continue operation.

I often get these access errors and I do not know why.
Any suggestions?
