Fixing Notepad++ 5.5 Langs.xml

November 6, 2009 / Patrick / 18 Comments

LangsXml Failed to Load I upgraded to the latest version of Notepad++ (5.5) and noticed that I sometimes get some problems with a dialogue box that pops up, looking like the picture the right stating (Load Langs.xml failed!)

Having a quick look at the installation directory, it looks like a langs.xml file exists yet it has a 0KB size. I’m not sure what causes it yet (perhaps it’s if you kill the process mid-way using Task Manager) but all I did was take a copy of langs.model.xml and rename the copy as langs.xml. Fixes it all up!

I had the same error, renaming the file fixed the problem indeed.
But, I had no problems at all, until I started using the FTP plugin.
Maybe the plugin is causing this…

Thanks! I also installed the FTP Plugin, im pretty sure this is the reason for it. 🙂

BTW, this problem exists in WinXP as well. The file on this system is 75,792 bytes large and has nothing but nul characters. The fix worked, Thanks! You could also erase/delete langs.xml and it will be regenerated.

I’ve got the same issue on Windows 7, but there is NO “langs.model.xml” at that folder! I just deleted the langs.xml, but it didn’t work!

Same problem and fix for me worked as suggested

close Notepad++
delete langs.xml
restart Notepad++

Notepad++ will refer to langs.model.xml and recreate a new langs.xml for itself.

If you have Arman’s problem as above, and you don’t want to do a reinstall, you could download the zip version of Notepad++, extract langs.model.xml to the install folder, then follow the fix.

I followed the suggested fix and get no massage anymore as I open the program, but the commands aren’t highlighted (C language)

I found an alternative: use the portable version of Notepad++ installed on a USB and wait for an update!

Thanks Peter

I have seen similar fixes documented at various places. For instance , you can find a similar solution here. While this certainly makes the warning message disappear, it doesn’t really resolve the issue that Notepad++ is corrupting, or wiping out the langs.xml file. Personally, I customize indentation settings, both the default settings, and in some cases the settings for specific languages. I have found that taking a backup of my modified langs.xml, and restoring it, will do the trick. However, I hope they can get this issue permanently resolved. I love NP++, but this has gotten a bit annoying.

the problem seems to reoccur, so i’ve created a .bat file as a one-click fix:

64bit:

download 64bit fixNotepad.bat
copy /Y "%ProgramFiles(x86)%\Notepad++\langs.model.xml" "%UserProfile%\AppData\Roaming\Notepad++\langs.xml"
x86:
copy /Y "%ProgramFiles%\Notepad++\langs.model.xml" "%UserProfile%\AppData\Roaming\Notepad++\langs.xml"
