MMC asks about 32- or 64-bit version

Whenever I start MMC, it pops up a window asking if I want to run the 32-
or 64-bit version. It shows two lists of Snap-ins and reports that 12 of
the 19 Snap-ins are available. (Where are the other seven?) The lists are
not quite identical; the 32-bit lists one Snap-in as "unknown" and the
32-bit list does not include "Service Dependencies" as the 64-bit list
does. It's behaved this way since the machine was new. Why?

"MMC (64) examines all snap-ins and extensions that are defined in the
console file and checks the registry to determine if they are available
as 32-bit, 64-bit, or both versions.

If equal number of snap-ins can be loaded with both, the user
is prompted to make a decision."

Apparently mmc takes a /32 command line option, but I would guess
it would be a lot of work to sprinkle that all over the place.

And there was a conversation back in 2012 about it.
But no magic Regedit setting to have it prefer one
choice over the other.
