simple question - I have been asked to click onto the key icon in system mechanic, but there is no key icon
Colin, at the upper left what version of the product is reflected that you are using? It should be 18.104.22.168. The screenshot I have provided below shows what the top part of the interface should look like, the key icon being off to the upper right. Clicking on the key and then Product information will show you your product activation information. If the interface looks different than this, click on the question mark instead and then Activation key.
OK sorted - thank you.
