Toshiba Satellite laptop
Vista Business
Sibelius 5 installed plus JABB

On this machine I use the ASIO4ALL driver, currently v2.9. This makes
playback using Kontakt Player 2 acceptable.

In Playback Devices I attempt to activate KP2 and the JABB soundset.
Error message "Installation folder is not writable, select a folder
now". If I select any folder, all appears good. But no playback
sound. (What folder should I be selecting?)

I change to the MME driver for the onboard sound. Now I have
playback using either the MS Synth or KP2/JABB. But KP2 is unusable
with crackling and breakup.

Sib. 6 demo works perfectly on my desktop machine using Windows XP and
a proper soundcard.

I hope this is purely a quirk of the demo version?
