Turn off Windows Defender for 1 min, then run NF, then turn on Windows Defender.On my computer that worked.

Also english TNF does not exist anymore, support is dead or nearly dead.I dont get response for my ticket for month, and it looks my problem wont be solved. 

Well, thats bad - but maybe you have some antivirus who is also blocking NF updater?There is a trick which can be used if you have access to other computer with correctly running NF, but its rather useless since having doing this procedure require a lot of time, and must be repeated after every update fail - make ISO file of HD on correctly tunning PC with NF and write it on your computer.But i am not sure if it works on win10 (this trick works almost 99% on win XP).

Wait, try also turning off windows defender from start and check if you can run game while windows defender is OFF. 

Well, maybe then try to reinstall game?Go to NF folder and move screenshots to other folder, then uninstall game, clear registry (command prompt and type "regedit", then search and remove all NF ,SDE,Kupaisky etc things)and try to install it again.

Well, i am out of ideas to help, sorry.If you keep getting msg that windows defender is detecting main.dll as a trojan, even if you turned windows defender off, then it looks that sth is bad with your windows, but its hard to help remotely about that.Maybe you need to reinstall your windows then (i guess you scanned your whole comp with antivirus soft already).

probaste que alguin te pase el archivo solo por correo o por otro lado?
