Hi all I'm moving over to use a Mac. I'm trying to install Sibelius 7.1.3 on a MacBook Air with macOS Sierra 10.12.1 I got the message: "The installation failed. The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance." Any idea? Thanks in anticipation! Peter
I ended up paying £19.95 to Sibelius for support (outrageous!). I was told what you just said - that it should work but it isn't supported. They told me to donwnload the installation files from the site rather than using the disk, and hey presto it then decided to work. I think however I will save up some pennies and buy version 8!
