Well in my impression Oracle 12c has a habit to put many obstacles for uninstall. :mad: If you find the right spots, it is still manageable. Keep in mind that you have to open the Windows CMD as Administrator. Otherwise the uninstall just goes south. In my case I had to enter at my installation path
C:\Daten\oracle\product\12.1.0\dbhome_1\deinstall\deinstall.bat
