I want to know if there is a translation text file for the french language(1036) and how to get one. I have actually installed a french language module for a client in nav 2013 but that does not change the object captions to french apart from department, home and role center links.
By "langauge module" do you mean the French sub-folders in the client and server folders?
Then you still need to import the French language translation. If you open the French Cronus localization and from the Object Desinger selects Tools -> Language Module -> Export. Here you specify a file name and the language (FRA).
When that's done, then you open you your actual development database (NEVER DO THIS IN PRODUCTION). Here you import the file you just exported.
Notice that you need a Partner Development license to do this, and you will have to recompile all objects again.
