Hello, I already had an activated version of 2019 Pro Plus, however I have changed my SSD to a new machine. While everything worked fine, the office license activation got deactivated due to hardware change. I was able to get a retail key to activate the license however I am getting the following message while trying to apply the key for activation. "This product key can;t be used to activate volume-licensed versions of Microsoft Office Professional Plus 2019. To use this product key, contact your administrator". So is there a way I can change my office installation (already setup and working properly) to retail version so I can use the key for activation. Thanks for your guidance.
