Hello, I'm helping a professional musician, percussionist and arranger get set up with Windows 7 and Sibelius 7 and we need to know how to make this as successful an experience as possible: 1, Which version of windows 7 will work best with Sibelius 7? He has an iMac with a 64 bit processor. 1.1, Can the Mac boot from an external drive on which Windows 7 is installed? 2, Given the current state of accessibility, will he be able to obtain back versions of Sibelius which are almost fully accommodated by Dan's scripts? 2.1, Exactly how will he go about doing this? Whom should be contacted? Help much appreciated.
