How to install Office 2019 on Windows 7 or 8

September 15, 2020

For a variety of reasons people still uses Windows 7 on their computers. Some are using outdated hardware that doesn't go well with Windows 10, some others prefer the classic interface, and some users dislike the new update system.

Whatever your reason is, we will explain in a simple way how to install Office 2019 in Windows 7 or 8, even when these versions are not officially supported.

Install Office 2019 on Windows 7/8

Although many people still work perfectly with previous versions of Windows, Microsoft is trying to put pressure on them to do the upgrade.

This implies that essential apps like the Office 2019 suite dropped official support for versions prior to Windows 10.


Fortunatelly, this doesn't mean that there's no method to make it work 🙂

Download Office 365 and convert it to Office 2019

Although the Office 2019 installer shows an error when we run it on Windows 7, the Office 365 one runs flawlessly.


So we recommend you to download the Office 365 installer and then set up the license files to activate it as Office 2019

This is the safest method because it avoids using any third-party tools or scripts.

Downloads from Microsoft servers are scattered around the web, so we have grouped them in a section by language to facilitate their download.

Easily mount .img files on Windows 7

Windows 10 allows us to mount ISO or IMG files using the native file explorer, so we don’t need another tool. But that’s not the case for Windows 8 and 7.

Fortunatelly there's a tool at our disposal called WinCDEmu. We recommend the portable version that's a single executable ready to launch and do it's job.

Once you launch WinCDEmu, it will require confirmation to install the required driver.


Click on the “Mount Image” button and find the location of your Microsoft Office .img or .iso file.


Once the installation finishes, you can proceed to activate Office.


Activate Office with the command prompt (CMD)

Step 1. Launch a CMD instance with administrator privileges from the start menu.

Your Office files are located in the following path, depending on your system architecture.

32-bit version: "%ProgramFiles(x86)%\Microsoft Office\Office16"

64-bit version: "%ProgramFiles%\Microsoft Office\Office16"

Step 2. Go to your Office location folder using the cd command


cd "%ProgramFiles%\Microsoft Office\Office16"


Now proceed to install the license files

Step 3. With the command /inslic you can install the required licenses for Office 2019 Pro Plus

Copy and paste this command on the console, then hit enter.

cscript ospp.vbs /inslic:"..\root\Licenses16\ProPlus2019VL_KMS_Client_AE-ppd.xrm-ms"

Same with these two

cscript ospp.vbs /inslic:"..\root\Licenses16\ProPlus2019VL_KMS_Client_AE-ul.xrm-ms"

cscript ospp.vbs /inslic:"..\root\Licenses16\ProPlus2019VL_KMS_Client_AE-ul-oob.xrm-ms"


This way you can install a product key for Office 2019 and it wont be rejected

Step 4. Use this command to install the product key

cscript ospp.vbs /inpkey:NMMKJ-6RK4F-KMJVX-8D9MJ-6MWKP

To activate Office with this 25-digit code we need to specify a server that validates the license

Step 5. With this command you set as the prefered host

cscript ospp.vbs /

It's recommended to use this server since it's the best known. If it's offline (unlikely) you can set instead.


Step 6. Lastly, run the activation with this command

cscript ospp.vbs /act

This is the message you receive when the activation is successful

Now you can enjoy all the Office 2019 features on your older Windows system!

At first launch, it will ask you once to type a code. Ignore this, as your software is already activated.

Frequently Asked Questions

Is this method safe and validated by Microsoft?

Yes, as the Office Software Protection Platform script (ospp.vbs) usage is described in this Microsoft document being part of the Office suite.

What does KMS mean?

KMS stands for Key Management Service. It’s a technology conceived by Microsoft to activate software deployed in bulk. For instance, clients connect to a KMS Server that validates licenses.

Is this activation permanent?

As long as you have a KMS server configured that remains active, you can keep the product activated for unlimited time. Just make sure you have an internet connection, as every 180 days the license is rechecked against the server.


There's no need to migrate from your older system to Windows 10 to enjoy the latest Office features. We've tricked Microsoft to be able to install it on Windows 7 and so far it works flawlessly.
