I have installed very last version of V4 series, it is working great. But it is only english. I dont find any langauge packages, for Exemple for german or french. Can someone give me link to download different language packs?
V4 will not get further updates and does not contain other languages. V5 does support multi language and we have an active project to allow community to contribute to translations that may not be available.
You dont change the files, many buttons in POS can be changed, you just change the button header in the automation command settings in manage - but manage section itself etc is hard coded.
