I've seen this before. To reproduce:

1. Install cygwin to some directory, say "c:\bizarro_path".
2. Optionally uninstall cygwin.
3. Install cygwin to another directory, "c:\cygwin"

The first install set up your /bin mount to point to "c:\bizarro_path\bin".

During the second install setup.exe places almost everything in
c:\cygwin. However the contents of /bin go to the existing mount point
at "c:\bizarro_path\bin". This is necessary so cygwin updates work when
you've mounted bin somewhere non-standard.

Specifically, when this problem happens cygwin.bat tries to run bash in
c:\cygwin\bin\bash.exe which is not there.

Simple enough to fix, just clear you mounts and reinstall.
c:\bizarro_path\bin\umount -a (IIRC)

I was thinking of submitting a patch to setup to warn users of /bin
being in a non-standard location relative to the install path, but
reasoned this is:

a) not a very frequent occurence
b) usually the user trying to do something strange*
