Sometimes if the langs.xml file gets corrupted you might get this error in Notepad++:

“load langs.xml failed”

Simple fix is to:
– Go to
%appdata%/Notepad++
– Rename langs.xml to langs_old.xml

Go to the official Notepad++ here:
https://notepad-plus-plus.org/download/

Find the download for your Notepad++ version.

Download the file named:
Notepad++ minimalist package 32-bit x86

Or the x64 version. It is a .7z file and can be opened with 7zip.
In this archive you’ll see a file named: langs.model.xml
Copy it to
%appdata%/Notepad++
and rename it to langs.xml.

If you like you can also keep the langs.model.xml file backup copy in case if the file becomes corrupted again.
Then open any file in Notepad++ and the error should be gone.

Hope this helps!
