    I found the solution here on the qt forums.

     

    My problem originated with setting the environment variables to get anaconda working.

     

    QT_PLUGIN_PATH=c:\Anaconda3\Library\plugins\

     

    But by setting this it breaks everything else. So for now I've just gotten rid of the path variable.

    To check if you have the env variable set

    1. Press <windows key> + R 

    2. Type "Control Panel"

    3. Open system

    4. Open advanced system settings on the left

    5. Click on the environment variables button at the bottom

    6. Browse through the user and system lists to see if QT_PLUGIN_PATH has been set.

Looking into similar problems for Linux QT based programs.

solutions:
Copy your AppData\Roaming\Dropbox\bin\plugins\platform folder, which contain the qwindows.dll file, into the AppData\Roaming\Dropbox\bin folder.

So new structure is: @
platforms\qwindows.dll
other.dll

Yours,
