The mercurial back-end for Qct does this when you start it up:

        # Find the mercurial binary name
        if findInSystemPath('hg') != None:
            self.hg_exe = 'hg'
        elif findInSystemPath('hg.cmd') != None:
            self.hg_exe = 'hg.cmd'
        elif findInSystemPath('hg.bat') != None:
            self.hg_exe = 'hg.bat'
        elif findInSystemPath('hg.exe') != None:
            self.hg_exe = 'hg.exe'
        else:
            print "Unable to find hg (.exe, .bat, .cmd) in your path"
            return -1

with findInSystemPath() defined as:

def findInSystemPath(filename):
    '''Search for an executable in the system path'''
    paths = split(os.environ['PATH'], os.path.pathsep)
    for path in paths:
        fullName = os.path.join(path, filename)
        if os.path.exists(fullName):
            return os.path.abspath(os.path.join(path, filename))
    return None

So the problem you're encountering is that Qct is finding a file 
named 'hg' in your system path, but apparently Windows doesn't think 
that 'hg' is an executable file.
