| From a purely functional POV, does native support for X64 really matter? Or more gently - is there some aspect of a 64 bit OS that prevents, or hinders a 32 bit app from performing it's job? Is there some inability inherent in a 32 bit app preventing it from doing it's job effectively when it's running on a 64 bit OS instead of a 32 bit one? | |

In short...No. If the version you d'load is for a 64bit system, the kernel mode will probably still run as a 32bit process, and it will Not affect your security in any way.
A 64 bit system runs identically to a 32bit system in many ways, that's why many 32bit programs run just fine on a 64bit system. The way some programs access/register/process/stream..etc, data is the only difference for a 64bit program, so things like CODECS need to be bit specific in that manner. Other than that, the only real difference for 64bit is the amount of data it can address in a single clock, since it has double the data width capacity (which is exponential of course)
