Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Tim,
Thanks for contacting us and sorry for the inconveniences,
- This problem may occur if the browser settings or extensions are interfering with the setup process. To avoid this problem, they suggest the following steps:
- Close all open windows and go to: setup.office.com
- Sign in using an existing Microsoft account or create a new one.
- Enter your Office product key.
- Follow the remaining instructions to install Office.
- This problem may also occur if the product key is invalid or incomplete. To check this, they suggest the following steps:
- Make sure that you received a 25-character code from the retailer.
- If the code is not 25 characters long, contact the retailer for a complete code.
- If the code is 25 characters long, contact Microsoft support via live chat to validate your product key.
I hope this helps!
Regards, Sola
