How can I change the UI language of Qt Creator 1.3.1?

I just downloaded and installed Qt Creator 1.3.1 on my English Windows 7 system from the english download site at http://qt.nokia.com/downloads Apparently, however, the UI of Qt Creator is in German language, although the help files are in English.

From the FAQ at http://www.qt.gitorious.org/qt-creator/pages/FrequentlyAskedQuestions I found the answer

Qt Creator uses the language setting of the system it runs on. On Linux systems you can also override that language by setting the 开发者_如何学运维LANG environment variable prior to starting Qt Creator, e.g. on the command line LANG=de ./qtcreator will run Qt Creator with german interface.

This, however, is apparently not correct, as I have an English Windows, and as system locale I have "English (United Kingdom)" set. Possibly Qt Creator interprets mistakenly the Windows settings for "current location", which I have set to "Germany" to mean that German would also be my language. However, changing that value had apparently no effect (maybe it should have been done before installing Qt Creator).

Is there any way to change the UI language of Qt creator to English after installing it, preferably without adjusting global system settings?

on qt Creator, go to tools->options->environnement>general

I managed to modify the language setting without reinstalling by adding an environment variable LANG with the value en_US (right click on "Computer", "Properties", "Advanced system settings", "Environment variables" on Windows 7).

qt creator 5.3.1
Tools->Options->Environment->General->Language
and select language what you want.

As mLar said but in German: go to Extras -> Einstellungen -> Umgebung -> Allgemein -> Sprache.

Another answer from qtforum.org. Go to [Qt_dir]\translations and rename appropriate designer_*.qm file, so that designer wouldn't be able to locate it.

Just add the variable LANG with the setting en_US to solve this problem in Windows 7 and Vista.
