So our Windows dev did some digging and this is what we were told.I've found the reason for the crash this person experienced when installing. If the service fails to start because the Listen() call throws an exception then the exception handler calls Close() and Close() fails to check if the handle pointer is a null reference before using it. What I don't know is why we are not able to start a named pipe on that persons machine. I'll add the missing check to the library code but that won't cure the actual problem they had, so I'll investigate further on what might prevent use opening a named pipe on Windows 10 Pro. I've never seen that fail before. So I don't think we have a general issue here, more likely a restriction configured on that machine or possibly the name we use for the pipe is already being used.
