TFTPD64 problem with running on Windows 10 PRO

Sep 18 at 8:45 AM
Hello,

I'm having issues with launching portable TFTPD64 4.60 ( 4.61 too ) on Windows 10 Pro.

There is not visible window with error:
Can't connect to the serviceError 10061 ( Can't establish connection, because remote computer is actively rejecting connection ) 
Any idea what can I do to run this app? It's allowed in firewall and I was trying to run it also with disabled firewall.

I never had such problems on Windows 7.

Greetings
