**this is the driver

extract and cancel the setup

then update driver using the extracted folder **

I did just that, and no longer had 'unknown' for coprocessor.

in Device Manager.

Navigate to the SMU and SMBUS folders inside the dell folder, wherever you've extracted it to. They''re nested inside the R273039 folder. Start at the Update Driver window in the unknown coprocessor entry in Device Manager.

Every is working great in Win 10 on a few of my MBPs... have been running Catalina, Mojave for over a year, thanks to the dos dude ;-)
