thank you for your replay.
I already try it.
It says that "it can not reinstall the software because there is already a newer one installed"
and it stops installing...

PS:I try with version 4,6
 
So you deleted that package. Did you try deleting other packages with DVDPlayer in the name?
 
No, I did try with the only one concerned by dvd player(found with Spotligth).

Has somebody an idea or a way to reinstall only this software without reinstalling whole the system?
 
Thanks to replaey.

To clarify the situation. I let just one pakage named DVDPlayerUpdate.pkg in the system. I tried to run it on my desktop or in the Receipt directory, the same message: "there is a newer version of the software..."

When it is says that there is a newer software,it is based on what?
What is the database of installed software equivalent to "windows registers 😱 database..."?
