This worked really well for Office 2024 Standard. Things were really smooth as long as you follow all the instructions.
Don't rush through or skip steps. I've installed this on a couple of new Dell laptops so far. It's a great option for people that aren't looking for the non-subscription version of the software.
It's really important that you uninstall any pre-loaded Microsoft Office products first from both control panel AND in Setting/Apps/Installed apps. I was overly cautious and uninstalled Microsoft Family and Teams also. The free version of Teams can be reinstalled after installing/activating everything but I wouldn't do it immediately after. You will likely get several prompts for activation during the whole process and once after.
The process of redeeming was relatively smooth and fast also.
