Repair Device Code 39 Errors

Device errors in the Device Manager indicate that there is a problem with either the device or the driver, causing the device to not function properly. The code 39 error is one such error code that shows the message “Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)“. The error message can have further details depending on the actual cause. Examples are “Bad File”, “Unable to Load Device Driver”, “DriverEntry Point Not Found”, and “Bad Image”, but it can also be a problem with a digital signature.

A code 39 error in Windows means one of the following:

  • A device driver is missing
  • A driver file is corrupted
  • A problem with the file I/O is occurring
  • One of the support files for the driver cannot be loaded

Windows drivers exist of a .SYS file and can be accompanied by .DLL files for additional functionality. If any of these driver files is missing or corrupt, a code 39 error can be the result. For driver installation the .INF file is critical as it specifies the version, operating system compatibility, installation details, and some other important information.
