Which apps are included in Office 2019 Professional Plus?

Office 2019 Professional Plus includes seven desktop apps: Word, Excel, PowerPoint, Outlook, OneNote, Access and Publisher. It's the most complete Office 2019 edition for Windows. Microsoft has announced that Publisher will no longer be supported after October 2026, so plan ahead if you rely on it.

App	What you use it for
Word	Documents, letters, reports and CVs
Excel	Spreadsheets, budgets, formulas and charts
PowerPoint	Presentations and slide decks
Outlook	Email, calendar and contacts
OneNote	Notes, notebooks and to-do lists
Access	Desktop databases (only in Professional Plus, not Standard)
Publisher	Flyers, newsletters and print layouts

What's the difference between Office 2019 Standard and Professional Plus?

The only app difference is Access: Professional Plus includes it and Standard doesn't. If you build or use Access databases, or simply want the full set, Professional Plus is the edition to choose. Both Office 2019 editions include Publisher.

	Office 2019 Standard	Office 2019 Professional Plus
Word, Excel, PowerPoint, Outlook, OneNote	Included	Included
Publisher	Included	Included
Access	Not included	Included
Runs on	Windows PC	Windows PC
Payment	One-time purchase	One-time purchase

A question we often get is whether Standard can open Access files. It can't: .accdb databases need Access, which only Professional Plus includes.

Should you choose Office 2019 Professional Plus or Microsoft 365?

Choose Office 2019 if you want to pay once and keep the same apps on one PC. Microsoft 365 is a subscription: it adds new features regularly, OneDrive storage and installs on several devices, but you pay every month or year. With an older release like Office 2019, also check the support dates below before you buy.

This key is for one PC. If you need the same edition on several computers, the 2, 3 and 5-key packs give you one separate key per PC.

Is Office 2019 still supported by Microsoft?

No. Office 2019 reached end of support on 14 October 2025. Since then, Microsoft no longer releases security updates or bug fixes for it. The apps keep working, but if you need a supported version, choose Office 2024, which is supported until 9 October 2029.

Office 2019 still suits buyers who need to match an existing setup, for example an office where every PC runs the same version. For a new installation, Office 2024 gives you the longest remaining support period.

What are the system requirements for Office 2019 Professional Plus?

You need a Windows 11 or Windows 10 PC with a 1.6 GHz dual-core processor, 4 GB of RAM (2 GB for 32-bit Office) and about 4 GB of free disk space. Office 2019 Professional Plus doesn't run on macOS.

Component	Minimum requirement
Operating system	Windows 11 or Windows 10 (and supported Windows Server versions)
Processor	1.6 GHz or faster, 2 cores
Memory (RAM)	4 GB (2 GB for 32-bit Office)
Storage	4 GB of free disk space
Display	1280 × 768 resolution
Internet	Needed for installation and activation

How do I install and activate Office 2019 Professional Plus?

Download and install Office using the link in your order email, then enter your 25-character product key when an Office app asks for it. Before you start, uninstall any older Office version or Microsoft 365 trial.

1. Uninstall any previous Office or Microsoft 365 versions from Settings → Apps.
2. Download Office 2019 Professional Plus using the link in your order email.
3. Run the installer and wait for all the apps to finish installing.
4. Open Word or Excel. When asked, enter the product key from your email.
5. Check activation under File → Account. It should show "Product Activated".

The most common activation problem we see is a leftover Office or Microsoft 365 installation, often a trial that came preinstalled on a new PC. Remove it, restart the PC and then install Office 2019 Professional Plus.

Frequently asked questions

Is Office 2019 Professional Plus a one-time purchase?

Yes. It's a one-time purchase with no subscription, and the apps keep working. However, Office 2019 reached end of support on 14 October 2025, so it no longer receives security updates from Microsoft. Choose it mainly when you need to match an existing setup.

Does Office 2019 include Publisher?

Yes. Both the Standard and Professional Plus editions of Office 2019 include Publisher for Windows. Microsoft has announced that Publisher will no longer be supported after October 2026, so it's worth planning a replacement if you use it a lot.

Can I install it on a Mac?

No. Office 2019 Professional Plus is for Windows only. Mac users need a dedicated Mac edition of Office, which uses a different product key. The Mac editions include Word, Excel, PowerPoint, Outlook and OneNote, but not Access or Publisher.

Can I move Office to a new PC later?

This key is for one PC. If you replace your computer, contact our support team with your order number first. Whether a transfer is possible depends on the licence type, so ask before you uninstall Office from the old PC.
