Guida all'installazione di Microsoft Office 2019 Professional Plus per Windows

Last reviewed 24 September 2026 by Justine, Technical Support Advisor at Nerdused (10+ years with Microsoft products). Meet the support team

This guide is for Office Professional Plus 2019 on Windows 10 or 11. Office 2019 is out of Microsoft support, so as well as the download and activation steps we explain what that means in practice and when it is still a sensible choice.

Microsoft ended support for Office 2019 on 14 October 2025. It still installs and activates normally, but it no longer receives security updates. If you want a supported version, Office Professional Plus 2024 is supported until 9 October 2029.

What you are installing

Edition	Microsoft Office Professional Plus 2019 (volume-licence release)
Apps included	Word, Excel, PowerPoint, Outlook, OneNote, Publisher, Access, Skype for Business
Not included	Teams, OneDrive storage and cloud features — those need a Microsoft 365 subscription. Office 2019 also lacks the 2021/2024 features (XLOOKUP and dynamic arrays in Excel, co-authoring, the refreshed interface).
Runs on	Windows 10 or Windows 11 (and Windows Server 2019 or later). Office 2019 does not install on Windows 7 or 8.1.
Minimum hardware	1.6 GHz dual-core processor, 4 GB RAM (64-bit), 4 GB free disk space, 1280 × 768 display, internet connection for download and activation
Version / channel	Office 2019 Version 1808, Perpetual Volume Licence 2019 channel. The installer downloads the final 2019 build from Microsoft's servers
Licence	This is a volume-licence build (the installer's configuration uses Microsoft's PerpetualVL2019 channel with product ID ProPlus2019Volume), so it activates with a Multiple Activation Key (MAK) rather than a retail key. Enter the key in any Office app under File → Account → Activate Product, or from an administrator Command Prompt: cd "C:\Program Files\Microsoft Office\Office16" then cscript ospp.vbs /inpkey:YOUR-KEY and cscript ospp.vbs /act. cscript ospp.vbs /dstatus shows the activation state.
Microsoft support	Ended 14 October 2025. No further security updates. Consider Office Professional Plus 2024 (supported until 9 October 2029)
Installer	2.9 MB self-extracting package containing Microsoft's Office Deployment Tool 16.0.17126.20132 and a configuration file; the Office files themselves (about 3 GB) download from Microsoft during Step 2

Download Office Professional Plus 2019

Pick your language and choose 64-bit unless you know you need 32-bit.

It is important to note that the key you have acquired is a prepaid code that does not work with the pre-installed software. This product is an authentic Microsoft offering.

Verify your download

Every installer is a self-extracting package that contains Microsoft's Office Deployment Tool (setup.exe, signed by Microsoft Corporation) and a small configuration.xml. Before you run it, you can check that the file you downloaded is the one we published: open PowerShell in your Downloads folder and run certutil -hashfile FILENAME.exe SHA256. The result must match the checksum below exactly.

Before you start

• Check Windows: Office 2019 needs Windows 10 or 11 — it refuses to install on Windows 7 or 8.1.
• Have your Professional Plus 2019 key from the order email ready (25 characters).
• Decide whether you really want 2019 on this PC: it is out of Microsoft support, so for a machine that opens email attachments and downloads, 2024 is the safer buy.
• Allow about 3 GB of download and 10–20 minutes.

How to Install Microsoft Office 2019 Professional Plus

Here’s a step-by-step guide to installing Microsoft Office 2019 Professional Plus.

Step 1: Uninstall Existing Microsoft Office (Required)

Before installing Office Professional Plus 2019, remove any previous versions to avoid conflicts.

1. Open the “Control Panel”.
2. Select “Programs and Features”.
3. Find Microsoft Office in the list, right-click, and select “Uninstall”.
4. Follow the uninstallation wizard instructions.

Note: The process may take several minutes, depending on your computer’s configuration.

Important: Restart your computer after uninstalling.

Step 2: Install Microsoft Office 2019 Professional Plus

After downloading the Office installer:

1. Go to your Downloads folder

2. Locate the installer file (Office_2019_EN_64Bits.exe)

3. Right-click and select Run as administrator

4. Follow the on-screen instructions

5. Select the “Install” button. This operation will extract the application and proceed with the installation of your product.

Step 3: Activate Microsoft Office

Method 1: Online Activation

1. Open any Office app, and you will be prompted to enter the activation key when launching any application from the Microsoft Office suite; this will be the initial request you encounter.

During the installation of Microsoft Office, you should have received a prompt to input the product key that we provided. If this prompt did not appear, please open Word, navigate to the File menu, select Account, and enter the key in the designated area. Failure to do so will result in your purchased Microsoft Office converting to a trial version after 30 days.

Method 2: Alternative Activation

1. Open any Office app

2. Go to File -> Account

3. Click Activate Product

4. Select Enter Product Key

5. Enter your product key

6. Choose Phone Activation

7. Take note of the Installation ID

Complete Activation via Microsoft Portal

1. Visit https://visualsupport.microsoft.com/

2. Click Let’s Get Started

3. Sign in with Microsoft Account

4. Select Activate a Microsoft Product

5. Choose Microsoft Office and Windows OS

6. Enter Installation ID

7. Obtain Confirmation ID

8. Enter Confirmation ID in Office activation window

Your Microsoft Office 2019 Professional Plus should now be installed and activated.

Common errors and the fix for each

• 0xC004F074 ("The Key Management Server could not be contacted") — The volume build is looking for a KMS server because no key has been entered yet. Enter your MAK with cscript ospp.vbs /inpkey:YOUR-KEY then cscript ospp.vbs /act from an administrator Command Prompt in the Office16 folder, or use File → Account → Activate Product.
• "Unlicensed Product" banner across the top of Word or Excel — Office installed but was never activated, or the 30-day grace period ran out. Go to File → Account → Activate Product and enter your key. If the key is rejected, send us the exact message shown.
• "We're sorry, Office can't install because another version of Office is already installed" — Click-to-Run refuses to install next to an existing Office or Microsoft 365 install. Remove the old version (Step 1 above, or the uninstall support tool), restart, and try again.
• "This product is not supported on this operating system" on Windows 7 or 8.1 — Office 2019 requires Windows 10 or later; it will not install on Windows 7 or 8.1 and there is no workaround. Upgrade Windows first (see our Windows 11 upgrade guide).
• Office 2019 stops updating — Expected from 14 October 2025: Microsoft no longer publishes updates for Office 2019, so the "Update Options" button reports nothing new. This is not a fault with your licence.

Questions we get about this edition

Is it safe to keep using Office 2019 after support ended?

It works, but from 14 October 2025 Microsoft no longer patches security holes in it. For a PC that opens files from the internet we recommend a supported version; for an offline or single-purpose machine many customers keep 2019.

Why choose Office 2019 at all?

Price, and compatibility with older add-ins or macros written for it. If neither applies, Office 2024 costs little more and is supported for four more years.

Does the 2019 key work on the 2024 installer?

No. Keys are edition-specific: a ProPlus2019 key only activates the 2019 build, and the 2024 build needs a 2024 key.
