Office 2016 Professional Plus Activation Key – 5 PC

Description

Office 2016 Professional Plus Activation Key for 5 PCs is intended for up to five eligible Windows computers using the matching Office edition. It is not a Mac product or a Microsoft 365 subscription. Before purchase, record the Windows version and determine whether each PC needs 32-bit or 64-bit Office.

Support status for Office 2016 Professional Plus Activation Key for 5 PCs

Microsoft support for Office 2016 ended on October 14, 2025. Activation does not restore security updates, bug fixes, or Microsoft support. Review the official Microsoft Office 2016 lifecycle page. Because unsupported productivity software handles documents, email, macros, and add-ins, assess security and compliance risks before installing it on connected or business-critical PCs.

Check all five Windows PCs

On each computer, open an existing Office app and choose File > Account > About to view the edition and bit version. Office applications installed together on one PC should use the same architecture. Therefore, do not mix 32-bit Office with 64-bit Visio, Project, or another Office release on that device.

• Platform: Windows PCs only; this Professional Plus edition does not install natively on macOS.
• Quantity: Plan no more than five eligible PCs and keep a private device-to-activation record.
• Architecture: Choose 32-bit or 64-bit separately for each PC, while keeping Office-family apps consistent on that PC.
• Edition: Confirm Professional Plus 2016 and verify the applications included by the specific product terms.
• Files: Back up documents, Outlook data, templates, dictionaries, macros, and add-in settings.

Digital delivery and activation support

Order information, activation details, and setup guidance are sent digitally to the checkout email after processing. Verify the address, retain the order number, and keep every key private. No physical disc or retail box is included unless the product page explicitly says so.

Install the correct edition and architecture before activation. If a supplied key cannot activate an eligible installation, contact support with the order number, affected PC number, Office edition, bit version, and error screenshot. We will verify the installation and key status. If the key is confirmed as non-working, we will replace it as needed until the eligible installation activates, subject to store terms. This policy does not extend Microsoft’s ended lifecycle or create additional device, transfer, or subscription rights.
