Hi Sure there can be different problems, but in my case Cura could not find glut32.dll that was included with Cura's installation package (in my case in C:\Cura_15.04.4\python\Lib\OpenGL\DLLS). I just needed to copy glut32.dll to C:\Windows\SysWOW64 The same advice in more detail. In my case the Cura's log was in C:\Users\\.cura\15.04.4\output_log.txt and the content was "Traceback (most recent call last): File "C:\Cura_15.04.4\python\lib\site-packages\wx-2.8-msw-unicode\wx\_core.py", line 14660, in lambda event: event.callable(*event.args, **event.kw) ) File "Cura\gui\splashScreen.py", line 15, in DoCallback self.callback() File "Cura\gui\app.py", line 103, in afterSplashCallback from Cura.gui import mainWindow File "Cura\gui\mainWindow.py", line 17, in from Cura.gui import sceneView File "Cura\gui\sceneView.py", line 28, in from Cura.gui.util import previewTools File "Cura\gui\util\previewTools.py", line 12, in from Cura.gui.util import openglHelpers File "Cura\gui\util\openglHelpers.py", line 17, in glutInit() #Hack; required before glut can be called. Not required for all OS. File "C:\Cura_15.04.4\python\lib\OpenGL\GLUT\special.py", line 324, in glutInit _base_glutInit( ctypes.byref(count), holder ) TypeError: 'NoneType' object is not callable" Similar problem was already discussed in http://stackoverflow.com/a/10797801 , but instead dowloading the package mentioned there I found required dll in the directory mentioned.
