It is definitely fixed. I will upload a test build within the next 10 minutes. Uploaded test build.
Before each update gets integrated, WinToolkit checks if it is already integrated and skips if true. The code which checks for IE10 Langpacks wasn't working and always reported as true so it never got integrated.
Now when a language pack for IE gets integrated, it checks if they're files in C:\\Program Files\\Internet Explorer\\fr-FR. If they're files in it, it will report back true. To sum it up, the langpack never got integrated as WinToolkit thought it had already been done.
