  ITYM '9009'?

'bash' is not recognized as an internal or external command,
operable program or batch file.

9009

  127 is a posix exit status, and if bash doesn't run, there aren't going to be any posix apps returning posix error status!
Perhaps "if exist" would be a better test if you just want to know if bash is there or not, but "if ERRORLEVEL 1" would hopefully
catch other problems apart from just missing bash.exe (missing dlls / segfaults in startup scripts... who knows?)

    cheers,
