How do I modify the default localized language files provided

 Either the localized language used is not provided as an optional user interface choice or is incomplete...

 Whilst we have endeavored to provide the most common language options - its a big world out there with many cultures and languages - and even specific language variations - its therefore very difficult to economically cater for every possible choice - particularly for those products we provide free of charge - such as the PDF-XChange Viewer, we therefore rely to some extent on the goodwill of willing volunteers and enthusiasts to assist us with these. In return we provide a free license to our flagship end user licensed product - PDF-XChange PRO (usual cost $74) in return for assistance.
 

 If you wish to assist us in providing new language file options or maintaining/extending incomplete files - we would welcome your assistance - please download the Language Localization Tool available from the download options offered  on either the PDF-XChange Viewer or PDF-XChange PRO download links, install to your local PC and see the help file provided (in English only).

Before proceeding - we recommend you email us to confirm that your intended language option is not already converted or for some reason cannot be supported.
