I have tried to install JABB in my laptop. OS is Vista 32 bit home basic version. Iinstalled the program and it came up and worked one time and when the program was closed a Microsoft message box came up stating that the Garritan application has stopped working correctly. Thereafter the program would not work. I tried this three times and got the same results.
I also installed Band in a Box and with a edirol VSC soft synth it works perfectly every time even though the same microsft box came up after each closing of the program.
