I just tried to run ./mach mercurial-setup on my Windows 7 box, and I got this:

$ ./mach mercurial-setup
Ensuring https://hg.mozilla.org/hgcustom/version-control-tools is up to date at c:/Users/mconley/.mozbuild\version-control-tools

(check hostfingerprint configuration)
Error running mach:


The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.

You should consider filing a bug for this issue.

If filing a bug, please include the full output of mach, including this error

The details of the failure are as follows:

CalledProcessError: Command '[u'c:\\mozilla-build\\python\\Scripts\\hg.exe', '--config', 'extensions.bzexport=!', '--config', 'extensions.bzpost=!', '--config', 'extensions.firefoxtree=!', '--config',

This smells like a duplicate. If it isn't, I know this was discussed and I thought addressed.
Summary: ./mach mercurial-setup on Windows raises CalledProcessError → ./mach mercurial-setup fails with hg.mozilla.org has unexpected fingerprint
Even if it is a dupe, this is still an open issue: the code in python/mozboot/mozboot/bootstrap.py doesn't set the fingerprints for hg.mozilla.org when cloning/pulling v-c-t. So if old fingerprints are pinned, you may get a mismatch.
