Proforms detects languages automatically. All languages are already included in the software package and must not be installed.
Because Proforms is based on Mailforms, we could adopt the Mailforms languages for the most part. We have expanded all new missing Proforms language elements of the front end language files. Missing elements of the back end language files have been added in English. Complete are the languages English and German.

We ask all users of Proforms in their own interest to send us the language files, should they have translated or improved the non-translated parts. If we publish an update it can happen that your translated files will be overwritten from the older version. We supply new language files including in update packages. If we provide single files to download on Mooj or via Proform's Helpdesk, these must be installed manually. Because Proforms is based on Mailforms and this used to be first released on Joomla 1.0.x the new kind of language installation is not built-in.
