Gears of War 4 UWP

[GTX590]

I'm actually working with CIUv3 but I'm still having issues whith this latter.
With CIUv3 install works fine but unistall no. I'm having an error message when clicking on uninstall button.

Runtime Error (at 510:2343)
Internal error: Unknown constant "sendto"

A second error message when exiting Unistaller:

Runtime Error (at 933:2148)
Could not call proc.

Can somene tell me if this is correct to use with Gears of War 4 (UWP game)?
