Hi @Jacky Gabriel
Thank you for reaching out to the Microsoft Q&A Forum.
Based on your description, I understand that you're trying to activate your one-time purchase of Office Home 2024 on a new laptop. However, you're getting an error that the license is already in use on another device, even after you've deleted and signed out from the old computer.
According to my research, there are two possible scenarios:
-The license came pre-installed with your computer. If your copy of Office was already on the computer when you purchased it, the license is tied to that original hardware and cannot be transferred.
-You purchased the license separately. If you bought the license as a standalone product, it is transferable. In this case, please try the method below:
According to Microsoft's official documentation, an Office 2024 license can only be activated on a single device at a time. If you want to transfer the license to another device, you must first uninstall Office from the original computer. Please refer to the following document for more details: This product is already installed on another device
First, you need to uninstall Office from the original computer using the following instructions: Uninstall Office from a PC
Next, please reinstall Office on the new computer and activate it using the process described in the "Activate after reinstalling Office" guide.
If the steps above do not work, please select the contact support to transfer your license to this device link from the This product is already installed on another device window
