If you bought multiple copies of Office and used the same Install button to install Office on multiple PCs, activation fails on the other PCs. This happens because each Install button is associated with a unique product key that can only be installed on one PC. To fix this, you can change the product key for the other PCs where you installed Office.

Note: After you change your product key, we recommend that you create a list to manage the product keys that you've installed. To learn how, see Manage multiple one-time-purchase Office installs that use the same Microsoft account.

    Tips:

    • The default installation for Office is 32-bit but if your PC has more than 4 GB of RAM, you probably have 64-bit Windows.

    • If you don't know which Office version is installed, see What version of Office am I using? To check whether Windows is installed as 32 or 64 bits, see Which Windows operating system am I running?

  6. Now start an Office app, such as Word, and select Next to activate Office over the Internet.

  7. Repeat this process for each PC where activation is failing.
