TFTP-Server under Windows 10 failed

If I'm translating that correctly, the error is saying something about the OS not being support?  Is that a correct translation?  Just want to make sure before I say anything else based on some rusty German I know. 

the_ben_keenis correct, which OS Version (Home / Pro / ...)  is used? What's the environemt. If you like to continue in German, we can do that as well. Kein Problem

I just installed it on my WIN10 Pro Version 2004 Build 19041.388 without issues.
