Failed To Install For No Reason

Random note that might be helpful (I just got randomly pointed at this issue and took a quick look over the code)

In IPCServer::RunThread the OVERLAPPED is an explicitly uninitialized variable OVERLAPPED connectOverlap;
This means its contents will be random-ish previous data from the stack, and may contain values sometimes that prevent the overlapped from working properly. MS documentation on OVERLAPPED dictates that it should be cleared:
"Any unused members of this structure should always be initialized to zero before the structure is used in a function call. Otherwise, the function may fail and return ERROR_INVALID_PARAMETER."

This could potentially cause the server to occasionally fail to ConnectNamedPipe, but then proceed to wait for the event associated with the OVERLAPPED despite the lack of connection. I suspect it could cause this error. The ConnectNamedPipe error would be logged in this case, but the server would be running and unable to respond to requests due to how the error is not propagated out of CreateAndConnectInstance

Suggestion is to zero-initialize the OVERLAPPED, that should prevent this failure mode.
OVERLAPPED connectOverlap = {};
