If the driver says it's not compatible, you may need to disable driver signature enforcement before installing the 2010-era driver.

This Hardware ID will confirm which driver you need.

: Choose "Browse my computer for drivers" > "Let me pick from a list of available drivers on my computer" .

Click and point to the extracted driver folder containing the .inf file. Select the RD9700 or JP1081 model from the list. 4. Troubleshooting Common Issues
