Signature Error (error code: -12)

I'm following the guide here, trying to get the sample project working on my device. After following all their steps, (connecting to my watch device and creating a certificate profile) when I try to run it on the device, I get the following error:

"The application installation on the device has failed due to a signature error! (error code : -12)

You need an appropriate certificate profile, which can be created or activated in the Certificate Manager. Do you want to open the Certificate Manager?"

I thought I did that already by following this.

Not sure what could be going wrong. When I try to run it on the emulator it works perfectly.

 

Any insight into this would be greatly appreciated.

Close all programs and reboot your computer. Press the "F8" key as your computer is booting up, before the appearance of the Windows logo. When the "Windows Advanced Options Menu" appears on your screen, use your keyboard arrow keys to highlight the “Disable Driver Signature Enforcement” option and then press "ENTER".

I hope this will be helpful.
