I have sent my query to Sibelius, but I thought I may get a faster answer here :) I am a 100% legit Sib. 4 user (swear on my 90mhz pentium 1's grave) but I lost my CD when I got married and moved apartments. According to the sibelius site, I will just need my product key to buy the Sib. 5 upgrade (which I have) So my question is, do you need to have sib. 4 installed to use the upgrade to 5, or does it come with a regular sib 5 CD for my installation pleasure?
The reason why I ask is because I would like the security of knowing I can reformat my HD, or buy a new computer and still be able to instal Sib. 5.
