Pythonw.exe cura Crashes !!! in Cura + plugins Posted July 10, 2016 Hi and welcome to the forum. It is pretty hard to tell what's up without knowing more. Maybe there is another software installed on your PC that interferes with Python on Windows. Start Cura again, let it crash and then take a look at the WIndows 10 event viewer viewer. Maybe there will be a clue in there. yes your right it was a PlayTV program all along who is doing the crashes i just find out hope everyone will see it.
