Some variation of
fc-list "Myriad Pro"> somefile
should get you a file you can run a test on.
And when the 18th output is on (writing to shell), you can put
\immediate\write 18{fc-list "Myriad Pro" > fontcheck.tex}
\newread\fontcheck
\immediate\openin\fontcheck="fontcheck.tex"
\ifeof \fontcheck …
in your main TeX file. (I tested only the first line).
and of course test the font names listed in that file in any way you please.
(Note I'm a Linux (Ubuntu) user and know not much about what font-list
command is available in other OS-es (and if any)).
Anyway, thank you Barry MacKichan for the tip: I asked the same question
on this list some months (years?) ago and the aswers were rather
unsatisfactory.
*This* looks it could work.

Hi Alan,
Is there a way to check whether a font is present in a user's
system? I need to generate a document with Myriad Pro if it exists,
Arial otherwise, and if neither, exit with an error.
Myriad Pro is nothing like Arial, though... but just to make your
life worse: thought about version numbers? There are many versions of
Myriad Pro, and many versions of Arial. How do you know which version
numbers are permissible?
Well, since I have no information on that, I'll assume that all are
useable.
But let's step back for a moment because there's a fundamental
problem with your question: if you're using TeX, you're implicitly
saying you care deeply about the typesetting of your document, which
includes being particular about which stretches of text use what
font. Not just "which various fonts look good for this text", but
"which font is the one I intend to use for this bit of my document".
Rather than testing for several fonts on a user's machine, and
picking "the best match", like if the content were styled via
(X)HTML+CSS, with a font rule that specifies various fonts with
fallbals, part of the power of TeX is the fact that it will always
look the same on any machine it's compiled on, provided the
dependencies are met. So, either your document will look the same no
matter what machine it's compiled on, or it doesn't compile. The idea
that it will compile with Myriad Pro on one machine, and Arial on
another, basically violates the very idea of TeX.
Sure, in an ideal world. But this particular application is to
conform to standards set by my university, and for better or for
worse, they've allowed Arial to substitute for Myriad Pro if the
latter is not available. And it may turn out that since I can
reasonably assume that Myriad Pro should be available, I can fix
things so that it is the only font used, as long as it can be found.
The better way to solve whatever problem you're having that made you
wonder how to detect certain fonts is to simply supply those fonts
along with your .tex source. If other people need to compile your
source, simply ensure that they have everything they need to compile it?
Well I don't know if redistribution of Adobe fonts is permitted (I
would assume not) so this really isn't a (legal) option.
