I want to transfer the product key to a new computer.

In my Office account, I have two keys. I have uninstalled the Office on the old PC like a lot of tutorials say. But installing from my account do not work and I still get messages like "Your copy cannot be activated... because it was already used...".

There was an advice on youtube to deactivate the key from the account. But there is no deactivate button on my account.

Can I somehow deactivate it from my account? Or are there other solutions to my problem?

If you are using one-time purchased retailed Office version, you can install Office on the new computer, then activate it by using Telephone on your new computer and uninstall the Office product from old computer.

  • FYI: (a) office 365: go to your Microsoft account, Installs page and sign in using your Microsoft account, if prompted (b) office perpetual: There is no way to deactivate Office Home & Student, Office Home & Business, Office Professional, or individual Office apps. Instead, you must reinstall and activate using the process described in Activate after reinstalling Office. – JCM Jul 27 '20 at 13:00
