"Windows cannot verify the digital signature for the drivers required for this device. ..."

Solution

• • The ONLY way to solve this problem is to DEACTIVATE Deactivate "SECURE Boot" in the PC BIOS.

Note

• • We are working on an update of the driver signiture but therefore a new Code Signing Certificate is necessary and
    the signing proceedure hat to be changed.
    As soon as we have setup this new proceedure we will offer an updated driver.
    
    or
  
  
  • Download the updated "cifX Driver Media CD - NXDRV-WIN CD V1.3.0.0 W10_SecureBoot.zip",
    uninstall the actual driver and install it again from the updated media (V1.3.0.0 (NXDRVWIN)).
