When i tried to install NB 3.5+j2sdk, the installer quit without previous advise, neither graphical nor by console. with NB 3.6 happened something similar, graphical mode didn't work, and by console quit as well, then i used the -silent flag, and it was supossed to be installed, but when i try to exec ./runide.sh, nothing happens, it doesn't even show a error message, just quit. I set the environment variable JAVA_HOME, and obviously for NB 3.6, i installed j2sdk1.4.01 before. I hope You could help me Thanx!!!!
