And nothing happens. It just sits, I have reinstalled it, removed my jar, reinstalled, restarted comp... everything. Any idea what I can do to fix it?

No, I'll try that right now. do I want 32 or 64 ?

How do I know?

Okay, I have installed the new Java 64 bit, I still get the same thing, should I just delete my minecraft file (With 1.5.2 old jar.) and just redownload it?Aha, I got it to work! Thanks for your help<3
