Save a Copy of package as with SQL server 2012

Hello,I want to save a copy of my package on sql server.

I use this procedure : http://msdn.microsoft.com/en-us/library/ms137565(v=sql.110).aspx

But the dialog box is not the "Save Copy of Package" with package location, but it's the dialog box to save on the disk.

I can't save on sql server.

Can you help me ?
