I think I tried everything. From discussions on discord, seems I should have some files in _nclapp folder, but I have only empty Cache folder there instead.

FAQ
-Is launcher downloaded from website or by old launcher?
-Tried both, same results. Tried different install directories, Program files, system disk, external disk. Same case on different computer that have Win7 instead of my Win10 laptop.

-Admin rights?
-Yes in all cases.

-Did you let launcher install extra thingies, .net, directX
-Yes. On win10 laptop there is .net 4.7 preinstalled and I shouldnt be able to install older one, but it gave me no errors.

-Delete all neocron related things with reg cleaner and try again.
-Done that, didn't help

-Try compatibility mode
-Win7, 8 compatibility mode don't work.

-Try to copy launcher files from the person where it works
-Tried that, launcher appear in task manager then it closes. Windows log throws .net runtime exceptions.

-Delete things in AppData folder in Neocron Support Team
-Done, nothing happens.

Is there anything else I can do? I'm locked out of game completely.
