  • In Windows 7, click Start -> Control Panel -> Hardware and Sound -> Device Manager

  • In Windows Vista, click Start -> Control Panel -> System and Maintenance -> Device Manager

How to Install drivers using Device Manager

  2. Select the Driver tab.

  3. Click the Update Driver button and follow the instructions.

In most cases, you will need to reboot your computer in order for the driver update to take effect.

Tech Tip: Driver downloads and updates come in a variety of file formats with different file extensions. For example, you may have downloaded an EXE, INF, ZIP, or SYS file. Each file type has a slighty different installation procedure to follow.

If you are having trouble installing your driver, you should use the Prolific Driver Update Utility. It is a software utility that automatically finds, downloads and installs the right driver for your system. You can even backup your drivers before making any changes, and revert back in case there were any problems.
