I today install SP1 on my Windows Server 2008 R2, but after the mandatory reboot are the MySQL server unable to start, where i get the following error.
C:\Users\Cronjob>"C:\Program Files\MySQL\MySQL Server 5.1\bin\mysqld" --defaults -file="C:\Program Files\MySQL\MySQL Server 5.1\my.ini" 110411 17:51:28 [Warning] '--default-character-set' is deprecated and will be re moved in a future release. Please use '--character-set-server' instead. 110411 17:51:28 [Note] Plugin 'FEDERATED' is disabled. 110411 17:51:28 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: 'open'. InnoDB: Cannot continue operation.
I have tryed to remove the "read only" on the data dir "C:\ProgramData\MySQL\MySQL Server 5.1\data" but this dose not help.
Any idears to how i can fix this?
