If you’re seeing a yellow exclamation mark next to your PCI encryption/decryption controller in the Device Manager, you’re not alone. It indicates something is wrong with the driver for this device, and you need to install a compatible, correct and up-to-date driver.
We’ve put together 3 easy ways for you to update the PCI encryption/decryption controller driver. You can simply choose one according to your needs.
- Update the driver automatically (recommended)
- Update the driver via Device Manager
- Download and install the driver from the manufacturer
Option 1 – Update the driver automatically (recommended)
If you’re not comfortable playing with device drivers, we recommend using Driver Easy. It’s a powerful tool that detects, downloads and installs any driver updates that your computer needs.
Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing.
You can update your driver automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 steps (and you get full support and a 30-day money back guarantee):
1) Download and install Driver Easy.
2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
3) Click Update next to the flagged device driver to automatically download the correct version of that driver, then you can manually install it (you can do this with the Free version).
Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).
If you need assistance, please contact Driver Easy’s support team at firstname.lastname@example.org.
If you want to update the driver on your own instead of using a driver updater, check out the next option.
