Hello

How to download correctly Mods for this game.

I tried to do it through NMD but it couldn't find the correct path.

I tried to find different paths in my PC but it doesn't work. also I can't find the correct exe file.

In my case : D\The Witcher 3 Wild Hunt GOTY.

FYI I shared my HD into 2 partitions C/ for application and D for my games.

Thanks for you help.

downloading and applying mods are two different things.

downloading mods - read the documentation on the website you got it.
application - make sure you have sufficient write privilages.

You're right.

My explanation was not clear.

When I run Nexus Mods Manager for the first time. The soft is trying to find all games in my PC showing the path.

For Witcher 3 it cannot find it as this game doesn't exist. I wrote the path manually. : D\The Witcher 3 Wild Hunt GOTY..
I'm not sure this is the correct path because in this folder I can't find any exe file.
I heard it was necessary if mods must work.
(I also created a folder named "mods".)

Please could you clarify me.

Thank you.

when you install the game, it creates registry entries. normally if it has issues, even when you manually point to it, it means the registry seems a bit off.

did you move it after installing?
perhaps used galaxy?

if you're simply trying to locate the exe, try following this path as a guide

c:\Program Files (x86)\GOG Games\The Witcher 3 - Wild Hunt\bin\x64\witcher3.exe.

This is not a problem for gog.com. This is a problem for Nexusmods.com.
