Yeah it happens to me also!!
When I start my game with iphlpapi.dll in the game directory, a new window titled 'Fatal Error' that says: 'Steam must be running to play this game!' pops up.
This is a problem that I found have overlooked.
There is only a few other threads out there asking for help but all don't have any fixes that work for me
Any fixes would be very much appreciated and tried out by me!

Have you found a solution?
Outdated DLL download the new version (iphlpapi.dll)
Empty for now
