I just tested the default installer (pretty much everything enabled) that was built by my nightly dartclient (Windows 7, MSVC 2012, Qt 5.2.1). To get the Workbench up and running I had to manually copy a few files from my Qt installation to the bin folder of the MITK installation:
- platform folder (only qwindows.dll)
- sqldrivers folder (only qsqlite.dll)
Furthermore I had to move all MITK plugins from the plugins folder into the plugins/Release folder.
