I get no error during installation! everything goes well.
but in the inteface symantec backup exec I can start "Install options and license on this server symantec backup exec".
thank you for the time you gave to answer my question and excuse my english.
I can not start the interface to install my licences.So i have done differently:
I started the install of symantec backup exec 2012 and I could install the licenses as if i installed for the first time.
