[Elecraft] Possible utility program conflict?

[Bruce McLaughlin]

After some time noticing that my K-3 was looking rather lonely sitting all
by itself on the operating desk I felt that it would greatly benefit from
the addition of a sibling.  Hence, I ordered a second K-3 fully loaded.

It then came to me that perhaps the utility program may be confused by
presence of the two radios.  When it comes time to update firmware will the
single utility program "know" which radio it is dealing with or is
necessary, and possible, to have a second copy of the utility program on the
computer, one for each radio?  The configuration of the two radios will be
slightly different with a different lineup of roofing filters in each.

Somehow, I think one copy will be sufficient but since I have yet to
encounter this situation I thought it would do no harm to ask.  Any
information would be gratefully received.
