Hi Dan, I think it would be safe to say that the vast majority of new systems sold now will be 64 bit. However, that does not necessarily mean that users will install a 64 bit version of Windows on them. I can attest to this as I have a laptop myself which is 64 bit, but with 32 bit Windosws 7 Ultimate on it - what a waste!!!

Dear all, I need to know how many users will need the solution for Sibelius 6 to run on a 64 bit machine. If you are using a 64 bit machine yourself, then you should reply with a simple confirmation. You should also reply to this if you provide a service to other 64 bit users who do not follow this list so that I can get an accurate count. I need this information as soon as possible since it will have an impact on the release date. Many thanks for your help, Dan Rugman.
