I've been running Sibelius 7.5.1 on an iMac Retina 5K (2014) and on an old MacPro. I replaced my old MacPro with a brand new iMac Retina 5k this past week. I unregistered Sibelius 7.5.1 on my old MacPro, installed and registered Sibelius 7.5.1 on my new iMac Retina. So far so good.
However, I am unable to install the Sibelius 7 sounds (25GB download). I've downloaded and tried the installation twice (the second time, it took MANY hours to download the 25GB package installer even though I'm on a 240+ Mbps download pipe). When I run the installer, I get an error:
ERROR: Installer data folder is missing ('Installer data').
Has anyone seen this? What's the solution?
Thanks.
