Notes: 1) This step also installs the special application and USB driver.
2) Note that the explanatory images below are those when using Windows XP.
Execute (double click) the saved Relay-Key.msi file.
The installation screen is activated. Execute the installation as instructed on the screen.

Once the installation is completed, a shortcut icon is created on the Desktop. A computer-resident icon appears (in the system tray in the lower right corner of the Desktop screen) when the created shortcut icon is executed (double-clicked).
This completes the software installation.

Note: Though it is not necessary to reboot the computer after completing the software installation, please reboot if instructed to do so due to the environment of your PC.
