Symptoms

The Code 28 error is one of several Device Manager error codes, thus this indicates a problem with the installation of an external device. The Code 28 error will almost always display exactly like this:

The drivers for this device are not installed. (Code 28)

The first thing to try with regard to this error is to attempt to clean the registry of your computer. A good way to do this is to download the Total System Care, which will do an excellent job of cleaning your registry and often sort out the problem in itself.

 

More Information and Manual Resolution

The first thing you can attempt with regard to this is to simply restart your computer which will often right the fault.

If this doesn’t work then another possible cause could have been the recent installation of an external device. Uninstall any recently installed devices and then reboot your machine. If this corrects the problem then reinstall the device.

If the problem persists, ensure you have downloaded the most recent driver for the hardware. If you still have problems then contact the manufacturer of the hardware.

Another possible issue can be whether you have the correct driver for the correct operating system. Ensure that you have downloaded the 32-bit driver if you have a 32-bit version of Windows, and the 64-bit for the 64-bit version.

Next install all of the latest Windows updates, and the latest Windows service pack. This could well contain a patch for the Code 28 error.

If this doesn’t work then the next option worth attempting is to use system restore function. This will reset your machine to a time before the error caused your machine to malfunction. You can then re-install any devices or programmes that have been removed by this virtual step back in time. System restore can be accessed through the Start menu, by simply typing “System Restore” into the search box.

If the system restore utility will not run correctly then you can attempt to activate safe mode. To activate Safe Mode, hold F8 when your computer is initially booting up. Once you’ve reached the desktop in Safe Mode, type ‘System’ into the Start search box and press Enter once ‘System Restore’ is highlighted. You should then be able to run the system restore utility.

If none of these steps work then you have to face up to the reality that it is probably a hardware problem, most likely with the external device. Contact the manufacturer of the device for further guidance.
