Subject: [Qt-creator] How to downgrade from 19.0.1 back to 19.0.0?

Hi,

first all sorry for that regression (not being able to override the system locale with "English" - all other languages work...).
You have several options:

- Check the workarounds given in the comment on https://qt-project.atlassian.net/browse/QTCREATORBUG-34457 to get English back in Qt Creator 19.0.1 even with German system locale.
- Download and install the fixed Qt Creator 19.0.2 snapshot from https://download.qt.io/snapshots/qtcreator/19.0/19.0.2/ . Use the "Link with Qt" (https://doc.qt.io/qtcreator/creator-project-qmake.html#register-installed-qt-versions) functionality to make the standalone installation aware of the Qt Online Installation.
- If you insist you can also use the same to downgrade to QtC 19.0.0 instead of installing the fixed QtC 19.0.2 snapshot. You find the offline installers at https://download.qt.io/official_releases/qtcreator/ .

You can run QtC with command line option `-language en`, e.g.:

C:\Qt\Tools\QtCreator\bin\qtcreator.exe -language en

it does work for me.
