at least looks like they dropping support for windows
"Orbit's focus has shifted to the Linux version. Windows local profiling is currently only supported partially and major features, such as dynamic instrumentation, are not yet implemented. It is possible however to profile Linux executables from a Windows UI instance. For Windows local profiling, you can still use the released binaries, but please note that they are deprecated and mostly undocumented."
