Locate your product or license details so you can activate after setup, and keep your internet access ready in case activation requires online verification. If you’re installing on a work or managed device, confirm whether your organization uses specific security policies or requires administrative approval. You’ll also want to back up important files and note any custom browser settings, since some Office components may prompt for permissions during the first run.
Download, install, and verify the Office suite
