protect xml or covet it to something and protect it

[moh]

Hello i have a software i translate it to another language, i want to be the only seller of it so how to i protect it with keygen , it's xml files, is that possible, anyone can help, note the .exe file is already protected

english.rar

I"d suggest this flow:

1) install orig SW

2) create installer with kg/pass/etc (of course installer should be not be reversable and should encrypt strong your text materials

3) installer will install extra language in case of valid flow

But if they copy the files they will be able to use the language right, because they have the activation for the software but only me i have this language then they can have the language if they copy it right?

Also orig sw i searched for this didn't find anything
