The installation is without problems. You can install the software separately in itself and other applications such as Kontact sampler of native or image score.
At config no problem to my knowledge.

SUITABILITY/PERFORMANCE

Sibelius 3 is running on athlon 900 Mhz 128 MB without problem

OVERALL OPINION

Used since its release, already adept since version 1.1.
the inteface is much nicer, the sampler is a native of better, but all instruments are not represented.
some bugs in version 2 are corrected.
very very intuitive and easy to access.
writing, the layout is facilitated by a large number of shortcuts.
a brief attempt
