To get the latest driver, including Windows 11 drivers, you can choose from the above list of most popular Prolific downloads. Click the "Download driver" button next to the matching model name. After you complete your download, move on to Step 2.
If your driver is not listed and you know the model name or number of your Prolific device, you can use it to search our driver archive for your Prolific device model. Simply type the model name and/or number into the search box and click the Search button. You may see different versions in the results. Choose the best match for your PC and operating system.
If you don't know the model name or number, you can start to narrow your search down by choosing which category of Prolific device you have (such as Printer, Scanner, Video, Network, etc.). Start by selecting the correct category from our list of Prolific Device Drivers by Category above.
Once you download your new driver, then you need to install it. To install a driver in Windows, you will need to use a built-in utility called Device Manager. It allows you to see all of the devices recognized by your system, and the drivers associated with them.
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. For more help, visit our Driver Support Page for step-by-step videos on how to install drivers for every file type.
When the scan is complete, the driver update utility will display a results page showing which drivers are missing or out-of-date. You can update individual drivers, or all of the necessary drivers with one click.
With automatic driver updates, you will save time and find the right drivers quickly and easily.
