Because you're talking about getting maximum speed.  Right now, 32-bit is
faster, therefore people will use 32-bit.  One can always recompile tomorrow if
a faster 64-bit compiler becomes available.

Too bad 64-bit Fritz 10.xx is not available today, or else you'd have a point.

That must be why they're using 32-bit binaries that are faster than ones they
can compile with 64-bit.  Gotcha.
