timesheet actualizer

  Can any one help me regarding the usage of time sheet actualizer. I am using primavera p6v7 and progress reporter.

Whether do i need timesheet actualizer for p6v7. i have searched in knowledge database. In one line it says we have to use time sheet actualizer for 6.1 or later versions. But at the last line they have given link to download actualizer which is available for 6.1, 6.2.

Do i need timesheet actualizer for p6v7 or not???
