serialnumber for Photostory 2015 Deluxe: Serial number removed by moderator. Please do not post confidential information in a public forum http://dl03.magix.net/photos2015deluxe_dlm.exe
You will see I have edited your post to remove the serial number you posted. This is a public, user-to-user forum, not a link to Magix support, and such personal and confidential information should never be posted here.
Unfortunately, your post doesn't make a lot of sense, since, apart from the fact you are asking something about Photostory 2015 Deluxe (which is now a rather old version) we have no idea what it is you need to know.
I might guess that you are asking about some "additional programs" that you were able to download when you originally bought Photostory 2015. Is that correct? If so, I would also guess that you cannot download them any longer. Is that also correct? The link you posted is for the installer of PS 2015 only; any additional programs would have been notified to you, perhaps by email, when you bought PS. You need to find that email if you wish to redownload those additional programs, though I strongly suspect that at least some of them may no longer be available.
