Update 17.1.2 doesn't install

Hello, and thank you for helping me.

 

Basically I'm trying to upgrade my driver from 16.12.2 to 17.1.2 through the AMD Radeon Settings.
Everytime, I start the upgrade, wait for it to finish, than restart the computer as asked, and when the computer boot up I get told that my current version is 16.12.2 and that I have the option to upgrade to 17.1.2.

 

 

I really have no idea of what is happening, please help

 

 

I have a desktop PC (with the latest build of windows 10) build by myself.

Graphic Card: AMD RX 480 Sapphire (being used since launch).
