UsbtinyISP on Windows ?

I just bought a usbtinyisp on I go the drivers running on windows 7 64 bit. But I really get to use the windows 8 version at home. So can anyone please help me get the usbtiny isp on windows 8? I'm pretty sure it's the newest version. On windows 7 x64 I used the windows 7 x64, driver from adafruit. The second driver. It's really hard to get the windows 7 laptop, b/c my sister is always using it. So I get to use the useless window 8 64 bit laptop. I really don't want to have to buy window 7 home premium version for like $75, and have reinstall avr studio 6, eagle cadsoft, arduino ide, and all my printer driver!. So, can someone please help me?!?!?!?!?!!?

I know this is very old post, but it is very similar to many on the net and I have been troubled by using USBTinyISP on windows 8.1 for 2 days. Luckily there is a solution and publishing it here could help others. Usual message was device descriptor failed, or something similar. I used libusbk to create the driver (libusb0 kernel driver package). or you can just download driver from https://github.com/overload0303993/USBTiny3.
