Windows
Greaseweazle is packaged as a Windows executable, hence there are no extra application components to download or install. Simply download the Greaseweazle host software, unzip, and run or add it to your PATH. Optionally, install the GUI application. The GUI does require the host tools, so you still need to download them.
Greaseweazle uses Microsoft's usbser.sys device driver. For Windows 10 & 11: The correct driver is automatically installed. Older versions may require drive installation (Zadig).
