Depending on the permissions. Maybe the user has no root rights on the PC.<br>

First, you're talking about "exe". You mean windows only? You want to use<br>
pyqtdeploy?<br>
<br>
QTranslator has a loadFromData which loads translations from an arbitrary<br>
string buffer. You can encrypt the .qm files and decrypt them before feeding<br>
the QTranslator(s).<br>
