[Bug 45749] Visual Studio 2017 Installer fails due to node.js/libuv listen (named pipe) error

https://bugs.winehq.org/show_bug.cgi?id=45749

--- Comment #1 from jimbo1qaz  ---
Corrections:
- `handle = new Pipe();` (PipeConstants.SERVER did not exist in node 8.9.3)
- node.js ships libuv. The relevant portion is located at
"deps/uv/src/win/pipe.c".

How is `handle` initialized, and why is `handle->flags` lacking
|=UV_HANDLE_BOUND?

handle = new Pipe();
- uv_pipe_init()

(unsure if called) if (!isNaN(instances)) {
handle.setPendingInstances(instances);
- uv_pipe_pending_instances() seems unimportant

handle.bind(address="\?\pipe\5d74...", port=-1);
- uv_pipe_bind() sets `handle->flags |= UV_HANDLE_BOUND;` if no errors occur
(and no errors occur in net.js/createServerHandle())

rval = createServerHandle(...
this._handle = rval;
this._handle.onconnection = onconnection;
this._handle.owner = this;
var err = this._handle.listen(backlog || 511);
err == EINVAL

So why isn't UV_HANDLE_BOUND set?? i don't have a clue.
