Begin by downloading the zip folder for Windows either from the WCH website or directly below.
A dialog box titled DriverSetup(X64) will open. Click INSTALL to begin the installation of the driver.
Once the installation is complete, a pop-up window will appear letting you know that the installation was successful. Click OK to close the window.
If you click HELP in the DriverSetup(X64) dialog window, you will get more details on the driver installation process.
Once you plug in your device over USB, the driver will complete its installation. That's all there is to installing the WCH USB to serial driver on Windows!
