Received "The application has encountered an unexpected error" when running firmware update

I wanted to post this in case anyone was having the same problem as me.  When prompted by SmartWare, I downloaded the latest firmware update ( for the MyBook 3TB hard drive.  I extracted the WDFirmwareUpdater.exe and ran it and received a dialog stating “The application has encountered an unexpected error and is now exiting”.  After troubleshooting and reinstalling the SES driver and reinstalling the drive, I was still receiving this error.

When I went back to the file, I noticed that there was a directory named “Ref” in the zip file as well.  When I unzipped that directory into the same location as the WDFirmwareUpdater.exe, the update ran with no errors. 

I know this seems like a dumb mistake to make but it cost me a lot of time and hopefully this post will save others time in the future.


I think you will need to contact WD support for this mate…sorry…
