[Paraview] CSCS_PointSprite_GUIPlugins fail to load on Win32...

[Kalle]

Hello,

When i try to load the CSCS_PointSprite_GUI plugins, which come with the 
win32 binary release from the bin\plugin directory error message pops up:

Plugin Load Failed:

The file '[...] CSCS_PointSprite_GUIPlugin_Server.dll' is not a valid Qt 
plugin

The same happens with CSCS_PointSprite_GUIPlugin.dll

My System:

Windows XP SP3 32-bit
paraview-3.6.1-win32 binary (installer) from the Paraview Website 
(Thursday 03/27)

TIA,

Kalle.

P.S.: The same happens with a self compiled paraview 3.6.1 on win32 :-)
