So when I try to start a server for zombies my thing just says "windows cannot find 't6rzm.exe'. Make sure you type the name correctly, and then try again" Does anyone know what I need to do. I installed all the stuff customized my server got admin and removed the perk limit but I can’t start my server. One of the staff in the discord server said it wasn’t connected to the exe file. I asked how I do that and I didn’t get a response for a while. I thought I just made myself look an idiot. Does anyone know how I can fix this. I made rules in the firewall with the port being the one that you use I can’t remember it off the top of my head. And it was UDP I made sure everything was correct. I watched a tutorial and I don’t know how to fix it. Can someone help? (I don’t know how to put images here).
