Part 1: How to Download Office 2019 Professional Plus

Office 2019 is distributed as a Click-to-Run (C2R) installer from Microsoft's servers. Here's how to download it.

Option 1: Direct Download from Microsoft (Recommended)

Step 1: Open your browser and go to Microsoft's official C2R download page:

👉 https://c2rsetup.officeapps.live.com/c2r/download.aspx?ProductreleaseID=ProPlus2019Retail&language=en-us&platform=x64&TaxRegion=PR&Source=O15PKC&version=O16GA

Step 2: The setup file (around 3–4 MB) will download. This is the "Click-to-Run" launcher, which will download the full Office 2019 suite during installation.

Step 3: Once downloaded, run the SetupRetail.exe (or similar) file.

💡 Tip: For 32-bit systems, change platform=x64 to platform=x86 in the URL.

Option 2: Office Deployment Tool (For IT Pros)

If you need to deploy Office 2019 across multiple PCs, use the Office Deployment Tool (ODT):

Step 1: Download the ODT from https://www.microsoft.com/en-us/download/details.aspx?id=49117

Step 2: Create a configuration.xml file with your settings (Office 2019 Pro Plus, 64-bit, English).

Step 3: Run setup.exe /download configuration.xml to download the Office files, then setup.exe /configure configuration.xml to install.

Part 2: How to Install Office 2019 Pro Plus

Step 1: Once the C2R setup file is downloaded, double-click it to start the installation.

Step 2: The installer will prepare, then download the full Office 2019 Pro Plus package (about 4 GB). This usually takes 10–20 minutes depending on your internet speed.

Step 3: When the download finishes, Office 2019 will install automatically. You'll see the message: "You're all set! Office is installed now".

Step 4: Click Close.

🎉 Done! Office 2019 Pro Plus is now installed on your computer.

Frequently Asked Questions (FAQ)

Is Office 2019 still supported in 2025?

Yes. Microsoft provides security updates for Office 2019 through October 14, 2025. After that, you can still use it, but no further security patches will be released. We recommend upgrading to Office 2021 or 2024 if you need long-term support.

What's the difference between Office 2019 and Office 2021?

Office 2021 includes the same apps as 2019 but with newer features like XLOOKUP, LET, and LAMBDA in Excel, plus a refreshed UI and better collaboration. Both are one-time purchases.

Can I install Office 2019 on Windows 11?

Yes. Office 2019 is fully compatible with Windows 10 and Windows 11.

Does Office 2019 Pro Plus include Access and Publisher?

Yes! Only the Professional Plus edition includes Access and Publisher. Home & Student and Home & Business editions do not.

Can I install Office 2019 on more than one PC?

No. A single Office 2019 Pro Plus license is valid for one PC. If you need Office on multiple devices, you'll need a separate key for each. For business volume licensing, contact DotKeys for bulk pricing.

Can I upgrade from Office 2016 to Office 2019 for free?

No. Each Office version requires its own paid product key. However, you can install Office 2019 side-by-side with Office 2016, and your DotKeys key is much cheaper than buying full-price.
