That attiny85.exe doesn't sound right. It should just be a set of zipped/rar compressed files to download.


Go through the instructions there and get the attiny core files from their github link in the text. I have gotten this to work on 1.04 and 1.01 Arduino IDE so you may have to get the right IDE install version from arduino.cc if you have something different. Mac or PC? Things get crazy if you are not using an UNO as your base arduino. Good luck.
