On my laptop (as in other 5 machines of friend of mine) the installer crash (quit) or block (Stop - I mean.. waited for 30min and nothing happened) when start to display the message "Running installation script" and none of us have been able to made it works after many time that we tried to re-run,re-download,re-delete old files and libraries...
...just to know, where did you get your installer and when?

No conspiration theory here! Just a little bit hangry for the lack of a contact option so that you cannot know if somebody it's working on the problem or not!
I really need it 'cause I'm working in Thailand (and I have to stay for long time) where other programs such AMule are not workings for unknown (to me) reason!
