Freeze on the first launch

[Asder99]

Hi!
I've just formatted a new computer, and I've installed Windows 7 x64.
I've installed winamp too, but on the first launch it freeze and close the application.

If I try to launch it, starts the skin setup, then file association, then the feedback. And everytime I click on "Finish" button, a window appear saying "Winamp is starting", but after 2 or 3 seconds Windows says "Winamp stopped" and closes it.

Where can I find an installation's log to find the problem?

Thank you!
