Error
Installing a service
[hudson] $ C:\hudson\hudson.exe install
WMI.WmiException: AccessDenied
at WMI.WmiRoot.BaseHandler.CheckError(ManagementBaseObject result)
at WMI.WmiRoot.ClassHandler.Invoke(Object proxy, MethodInfo method, Object[]
args)

ErrorControl , StartMode , Boolean , String[] )

I think this is caused by not having enough permissions to create the service,
but the error message could be better, perhaps suggesting to run hudson as
administrator. This is on Vista Business, 64 bit.
