Installing MiniCore went OK. But step 6 failed, the bootloader would not burn.
Initially the serial port section was empty until I reinstalled the USBasp driver using Zadig and installed libusb-win32.
Using the same USBasp I can burn hex files and read/write fuses using avrdudess, which provides a gui for avrdude.
Any ideas why the USBasp does not work from the IDE?
