Bad CPU type in executable & Failed chip erase: uploading error: exit status 1

[atlasmooth]

First, thanks for pulling this together.

Sadly, I am not able to burn the bootloader. I am trying to use this project library and instructions to program a ATTiny45 with a simple Keyboard sketch example

I am using an Arduino UNO as an ISP programmer, based on the instructions from highlowtech.org post. And I can load simple blink sketches with that setup.

I have other circuit ready with the Hardware setup you recommended. The space for the ATtiny45 is there waiting. But at the step of burning the bootloader, as instructed in the Software Setup, and still using the Arduino UNO as programmer, I get the following error

Library/Arduino15/packages/arduino/tools/avrdude/6.0.1-arduino5/bin/avrdude: line 4: /Library/Arduino15/packages/arduino/tools/avrdude/6.0.1-arduino5/bin/avrdude_bin: Bad CPU type in executable

Failed chip erase: uploading error: exit status 1

I hope you could give me a clue on what I am doing wrong. I hope provided enough context (let me know if I didn't)

using VUSB-AVR v1.0.1
Arduino IDE 2.2.1

this is my circuit to program the ATtiny with the Arduino:

thanks in advance
