Hi,

which version of the Qt SDK (not Nokia Qt SDK) did you try to install? I assume that this is the one, which contains Qt Creator 1.3.1? Because in that case we had some issues in relation to compatibility of the configuration files.
Could you try removing the qtcreator.ini in your home/AppData/Roaming/Nokia and reenter the Qt Versions after a Creator restart (preferrably the one from the Nokia Qt SDK).

In future releases we will prompt the user about this incompatibility and suggest this step during the installation process.
