If erwin is launched in Windows 10 (or Win Vista/8.1) using “Run as Administrator”, when a model is dragged and dropped into that launched erwin, the model is not opened. Why?
Run erwin as normal application (without 'Run as Administrator') and then try the above steps, the model will open in erwin without any problem as expected. It seems that Windows under elevated permission does not allow drag and drop functions to the application installed on it.
