I tried the demo on Vista last night. There is an opening dialog which contains a buy button. I'd suppose that when you went thru that process, you might be asked if this is a new purchase or an upgrade. Only a guess. js On Aug 2, 2011, at 10:31 AM, Claudio Sacco wrote: Hi all, Here's Claudio after a long time. I have downloaded and installed Sibelius 7; it is not perfect, but so excellent, that I wanted to upgrade from Sibelius 6 to Sibelius 7. But I haven't figured out, how to do that. If I enter the serial number of Sibelius 6 into Sibelius 7, it doesn't work. So I assume, that I have to buy the upgrade, but I didn't find, where to do that. If I have not to buy the upgrade, does Sibelius 6 have to be installed on the same machine to be able to upgrade to Sibelius 7? I have a new machine, where actually apart of Sibelius 7 trial, no other Sibelius versions are installed. I have unregistered Sibelius 5 and Sibelius 6 on my old machine. Does somebody know, how all this works? I'm ready to spend money for Sibelius 7, because I'm convinced, that development goes in the right direction. And may thanks to the developer and Dan, because I'm quite sure, that the developers learned from Dan, what are the needs of blind people.
