If the driver installer is available, you just have to click on the Setup.exe file inside the driver installer folder. However, if only the driver is available, do the following:
1. Go to Windows Device Manager.
2. Right-click on the AET62 or AET65 sub-entry of Smart card readers.
3. Choose Update Driver from the menu that comes up.
4. Choose to manually locate and install the appropriate driver.
Note: It is best to first uninstall previously installed drivers prior to installing a new one.
