What type of processor does your machine have?  If it has an Intel Core Solo or Intel Core Duo processor, rather than an Intel Core 2 processor, an Intel Core i{3,5,7} processor, or a Xeon processor, it's incapable of running the 64-bit version of Wireshark, as it's a 32-bit processor rather than a 64-bit processor.

If you start Activity Monitor from the Utilities folder in the Applications folder, and it doesn't show any processes as "Intel (64 bit)", you probably have a 32-bit processor, and must download the Intel 32-bit version of Wireshark (which is built on Leopard, but should also work on Snow Leopard).
