Hello,
To install a language, you need to do the following:
- Unpack the zip file
- Check the file name. If you are using version 1.x the filename should be en-GB.com_csvimproved.ini. If you are using version 2.x the filename should be en-GB.com_csvivirtuemart.ini. The en-GB can be different depending on the language. In this case it would be de-DE.
- Upload the files to the folder administrator/language/<your language>. Your language should be the same as the starting language of the file. For example en-GB or de-DE.
- All done
