I can confirm the V7.x installer error while updating the language files. I stuck every time at this point. The installer do a update to the files but dont display the continue button. You have to use the browser-back button and skip the next part wit 'do my own modification'. The rest runs fine. After this you have to check you language files by hand (I use beyond compare).
