Each build depends on the environment (msys32) - so use may cause incompatibility of the *.dll.
You have to accept the principle of not mixing (replacing) files from different sources.

The translation action is very specific to this plugin:
- the translation files should be placed in the lib\locale directory,
- place the folder "nufraw" in the c: \Program Files\GIMP 2\lib\gimp\2.0 folder and add it in the Preferences/Folders/Plug-Ins directory.
If you place the directory "nufraw" in another location, eg in the home directory .gimp-2.8 (also after adding this directory in Preferences)
will only work in English version.


It is also worth trying GimpLensfun (gimp-lensfun.exe).
