Step-by-step solutions
Find an updated official version
Check the model and Windows version before selecting a package.
Check driver updates available through Windows Update and the manufacturer’s official support. Choose only a version compatible with the device and Windows.
If the file came from an unofficial site, do not force it to run. Obtain the package from the manufacturer rather than random drivers or generic utilities.
Advanced checks
Continue if the earlier steps did not help. Read each procedure’s precautions first.
Update using the compatible package
Keep an alternative available for essential devices.
Save work and install the official update using the manufacturer’s instructions. If reinstallation is required, limit it to the identified device.
Restart if requested and check whether Code 52 has cleared. If signature verification still fails, stop rather than accepting an unverified driver.
Still not working?
If the latest official driver still shows Code 52, contact the manufacturer or IT. Specify the package and Windows version without modifying signature policies.
