Ensure you have removed all former driver per the instructions found in the manual before attempting to install this latest driver version.
After downloading the file, unzip the file into an empty folder or directory on the hard drive. (If you cannot locate the file you downloaded, use the Windows Find command to search for the BoomNPro_V3_driver.zip program on your hard disk.)
Do NOT connect the Boom'N Pro V3 to the computer, and run the setup.exe file to install driver. Restart your PC after driver installation completed. Your PC will automatically detect the Boom'N Pro V3 that is connected with provided USB cable and in power on. (This program will be found in the folder you unzipped the files to in step #1)
