Shareaza

I'm totally new to Shareaza. Haven't even installed it yet, because the official download page http://shareaza.sourceforge.net/?id=download confused me. Shouldn't there be a Shareaza 2.6.0.0 SSE2 optimized (64-bit) version? It seems like I have to choose either SSE2 optimized or 64-bit version, but I want both combined. So which download would be optimal for me? My system:

CPU: Intel Core i3 2310M
OS: Windows 7 64-bit

64-bit code always and everywhere includes SSE2 extension.

Oh, I see, crystal clear. Thanks raspopov!
