Description of the Issue

When installing 3P in Notepad++ x64, the plug-in looks for a file userDefineLang.xml in the %APPDATA%\Notepad++ folder. If the file is not present, the 3P plugin warns the user each time Notepad++ is launched.

The file userDefineLang.xml is NOT required by Notepad++ for default operation.

You can create a "NULL" userDefineLang.xml file containing:

and save it to the %APPDATA%\Notepad++ folder. If you do that, the warning goes away.

Steps to Reproduce the Issue

1. Perform a clean install of Notepad++ x64 (latest version)
2. Manually install the x64 plugin manager for Notepad++ x64
3. Using the x64 plugin manager, install 3P
4. Restart Notepad++
5. The warning dialog will appear if the userDefineLang.xml file is not found at %APPDATA%\Notepad++ path.

Expected Behavior

For the 3P plugin to load when launching Notepad++ without generating a warning that it can't find the userDefineLang.xml file in the %APPDATA%\Notepad++ path.

Actual Behavior

The warning occurs...
