Translations of QMessageBox not work in Qt5.3

Question

I\'m a fan of Qt and update it frequently, Qt5.1->5.2->5.3.

However, the tranalations of Standard buttons like \"Ok\" \"Cancel\" \"Save\" do not work anymore in Qt5.

Answer 1

This is source of qt_ru:

Therefore, it is necessary to deploy application with all these translation files. If at least one file is missing, the translation qt_ru will not load.
