Cant update my 3tb external

I have a 3tb usb3.0 external drive. It tells me that i have a update, so ive downloaded the update and im following the instructions, but i always get this message:

“The specific drive is in use. Please click Exit; then close all other open applications and run the WD Firmware updater again.”

Ive checked many times to see if i have any applications running that would be using the drive, but i cant seem to find any, although i still get that message. I would like to have my drive updated, since it apparently fixes the memory utilization issue.

Any help would be much apperciated.

Try to un-install the WD Smartware, once you do so, restart your computer and make sure that you Antivirus is disable, then, run the firmware update.
