After some more digging around it seems the ded is not seeing any of the other player folders , player1 player2 all have proper individual ports and have run nicely together for the last 2 years ..
I did a test and created a brand new player -"player5" , I set up the ports after changing the name to match the folder then went to the bin32 to launch the ded and choose player5 from the drop down( also tried in bin64) but these exe's give the "No Mods Found" error

… Is this where I'm supposed to make the short cut's for the ded's ? from one of the the bins depending on what bit you want right? .. ….. no joy there …
(remember this is a steam account on a rack service win2012R server with all our leagues games on it & never used as client, in fact it wont even launch the client side so no client action)
So i go back the the trusty rf2 launcher and hit the host button ,& when the ded comes up I try that player drop down to see if it will see the new folder i made or any of the other 4 player folders .. sadly none of the other player folders were in the drop down to choose from or its not allowing it
seems like Its like its not looking in the right place or something but the paths all match up .. do I need to edit the command line to have it see the other player folders?
I did not create this server set up I took it over 2 years ago and its ran fine until this update so IDK if maybe there was a command line that the new build removed ?
The old short cuts for the 4 servers are still there & when brought up they show the correct player like "player3" for the ded short cut named server3 but are also the only player folder in the drop down.. This is so strange .. I hope im just over looking something ..
It runs from the launcher so we can host 1 event ;-( but cannot get the multiple deds to work ..
