Hi, here is an extract from the documentation we are planning to add to shed some light onto the Qt Designer plugin issue. I hope it helps:
"...You can use Qt APIs to create plugins that extend Qt Designer. Qt Designer fetches plugins from the standard locations and loads the plugins that match its build key. For more information on how to create and locate plugins and to change the default plugin path, see {How to Create Qt Plugins}. Qt Designer is integrated into Qt Creator and in addition comes as a standalone application. The correct folder to place the plugins depends on which you use. The integrated Qt Designer fetches plugins from the %SDK%\bin\designer folder on Windows and Linux and QtCreator.app/Contents/MacOS/designer folder on Mac. Choose Tools > Form Editor > About Qt Designer Plugins. The standalone Qt Designer is part of the Qt library used for building projects, located under %SDK%/qt. Therefore, it fetches plugins from the following folder: %SDK%\qt\plugins\designer. To check which plugins where loaded successfully and which failed, choose Help > About Plugins in the Qt Creator. The Qt Creator that is included in pre-built SDK packages on Windows is built with the Microsoft Visual Studio compiler, whereas the version of Qt shipped for building applications is configured and built to use the MinGW/g++ compiler. Plugins built by using this version of Qt cannot be loaded by Qt Creator because the build-keys do not match. The plugins can only be used in the standalone version of Qt Designer. Choose Help > About Qt Creator to check the Qt version Qt Creator was built with. If you want to use Qt Designer plugins that were built for the shipped Qt version, you need to make sure that Qt Creator is built with the same compiler by either recompiling Qt Creator using MinGW or recompiling Qt with Microsoft Visual Studio, depending on which configuration you want to use for your applications."
