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 Macer_v1.0.zip program on your hard disk.)
Connect the Macer to the computer, and select "\Win98" folder when the system ask for the driver. Restart your PC after driver installation completed. Your PC will automatically detect the Macer 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)
