I'm afraid where "Minimum Requirements" are concerned, I generally take these to mean "AVAILABLE" resources. For example, I have a Vista Ultimate system here. I am only running Outlook (not even JAWS), and Task Manager tells me that 48% of my 1.5 GB of memory is in use. Roughly speaking, that's 750 MB of available memory. XP system may run with 512 MB, but by the time you add JAWS and other applications, your available memory is almost nil, and so the SWAP file on your hard drive is working overtime. Frankly, without adaptive software to consider, I'd personally never consider less than 1 GB of RAM in an XP System other than for very light use. Obviously costs where you are may be high, but in the UK and USA, memory is a relatively low cost commodity, and well worth the investment given the performance benefits.

You may be able to use Sibelius Sounds Essentials if your computer doesn't meet the recommended requirements, but you may find that you cannot use as many sounds simultaneously. The problem isn't on the sound at all, so, what do u think?
